Now patient rooms can easily incorporate dimmed lighting with a single button control found at most patient bedsides. Until 2001, UK wiring regulations required that all bathroom switches were operated by pull cords. Otherwise we’d have to install new, much heavier gauge #14 or #12 electrical wires to support 120V switching directly. 5. A dimmer controlling an inductive load such as a magnetic transformer is also subjected to large voltage spikes and current surges. The fixtures put out less light than line-voltage fixtures, and if the distance from the transformer to the farthest fixture is 100 feet or more, voltage drop can cause a dim, yellow light unless you use special installation techniques. Miscellaneous Switches and Dimmers. Touch switches have no moving parts and electronically switch the light circuit. Lutron manufactures low-voltage dimmers for low-voltage fixtures that use magnetic transformers. 4. While some ELV transformers are labeled as dimmable with standard incandescent dimmers” Lutron does not recommend this because the best dimming performance is achieved with Lutron® ELV dimmers or GRAFIK Eye® system controls. You can also buy Despard cover plates for your old and new Despard switches. Transformers reduce your home’s standard line voltage for use with low-voltage fixtures. Each switch is connected to it’s own relay (unless two switches have been wired together to a single relay for 3-way functionality). Note that your old switches may have wires attached via screw terminals, as shown here. Walk into any home center or garden center this spring and you’re guaranteed to run into a towering display of outdoor low voltage lighting. Whether you just want to buy a Kichler In-Line Low Voltage Light Switch or shop for your entire home, has a zillion things home. Lutron offers dimmers for both load types in a variety of product families. 3-Way Dimmer with Switches – 3-way dimmer adjust the light level from one location. Note that if you have more than 7 fixtures in a zone, you can use two hub connectors – the first hub connects to the transformer, the second hub connects to the first. Transformers typically require a minimum combined wattage in order to operate the lighting system effectively, and without flickering or humming. Power controlled by this switch. Product Description LVS low voltage switch, Type: Latching, Number of Buttons: 3, Pilot: No Pilot, Color: Ivory. The rough-in inspection consists of checking that all wiring is properly installed before any switches, fixtures, insulation and walls are added. If you are updating your broken, discontinued Bryant or GE low voltage light switches, or you’ve already updated to the new GE RS2 switches, you’ll need to buy new low voltage switch plates to fit the new switches. If your switches look like any of these original GE, Bryant or new GE low voltage parts, you will replace your relays, transformers, switches and switch plates with the new GE parts that we carry. AC power comes in on two wires, the hot and the neutral. Test each light fixture for its voltage level with a digital voltage meter (about $25 at Radio Shack). You can purchase New Style GE Low Voltage Switch Plates for your new switches and the switches will snap directly into the plate. The new switches snap into these cover plates, eliminating the need for a bracket. Each has pros and cons, but except for very large residential projects, low-voltage systems are usually a better choice. It allows for great lighting control while reducing energy costs. You can use Touch-Plate® switches in place of three-wire switches, but you will need two Touch-Plate® buttons for every one three-wire switch. Power window switches are a common example. Use waterproof pond lights for illuminating pools, fountains and other water features; offset path lights for lighting walkways; cone lights for highlighting both walkways and the surrounding plants; tree-mounted spotlights for simulating moonlight; and flood lights for illuminating trees, buildings and other large elements. Note: Line voltage incandescent and low-voltage fixtures can be mixed on the same circuit, but the correct low-voltage dimmer (for the given low-voltage load) must be used. Reverse phase control is for use with either capacitive (ELV transformers) or resistive (incandescent) load types. Figure 1. Task lighting can be a small work light for checking to see if the steaks are medium rare (top), or a chandelier that lights a friendly game of Texas Hold ‘Em (bottom). Check the building first for for sticking low-voltage switches. Product Description LVS low voltage switch, Type: Momentary, Number of Buttons: 2, Pilot: No Pilot, Color: Ivory. Equalizes voltage at fixtures. Due to the higher efficiency of ELV transformers, Lutron® ELV dimmers are rated in watts (W), which is the lamp load connected to the transformer. If you want to put ten 20-watt lights on a circuit, make a tee connection with five lights on one line and five on the other.
When you buy a Kichler In-Line Low Voltage Light Switch online from Wayfair, we make it as easy as possible for you to find out when your product will be delivered. Because of their compact sizes, these transformers commonly support low-voltage under-cabinet and cove lighting Magnetic transformers are larger. The more distant fixtures are also on a loop circuit, but the loop doesn’t start and end at the transformer — it starts at and loops back to the fixture in that circuit closest to the transformer, and a single supply line then runs back to the transformer. Although the switches had adequate ratings for usage on 120 V circuits and had advantages of compactness and distinctive appearance, they failed to establish themselves in the American market. To use these plates, first mount a new 1-gang bracket (houses 1-2 switches) or a 2-gang bracket (houses 3-4 switches). Low voltage relays may not operate reliably if exposed to below freezing temperatures, or to temperatures above 120 degrees. Low-voltage wiring reduces wiring cost by eliminating the need for expensive conduit. 2. Do not use regular incandescent dimmers for MLV lighting. Low-voltage systems do have a few downsides, though. Update your old GE switches with modern low voltage parts. If your lights still aren’t coming on, check to make sure your outlet has power. We invite you to follow us as we grow the SENSORWORX brand, build our new production facility, and create products that set The New Standard in Lighting Controls. Minor voltage adjustments can be made using the voltage controls on the transformer (Photo 2). Enjoy the beauty of your landscape (and sure footing) after sunset with low voltage lighting. This approach should be substantially less costly and troublesome than attempting to convert all of the switches in the home to 120V design – that would require re-wiring those areas in the home with new 120V wires. There are two different types of deck lighting systems: One operates on household voltage (120 volts, also called “line voltage”), and the other runs on low voltage (12 volts). The benefits of line voltage include lower-cost fixtures and light bulbs and easier installation. High Dry 100 ft. LED Tape Light allows the option of running three lengths of low-voltage LED tape or hard strips off a single power supply. Inspired by industrial systems that relied on relay switches to control motors, lights and other industrial equipment, vintage remote control wiring systems used relays to switch a current; these relays, in turn, were controlled by small light switches operating at a low voltage comparable to that of a doorbell. These low-voltage transformers are also usually rated for wet and damp environments, so you can safely install them outdoors. Product Description LVS low voltage switch, Type: Latching, Number of Buttons: 3, Pilot: No Pilot, Color: Light Almond. Switching relays that are too hot or too cold may not work properly. Because the relays only required a brief impulse to switch the current, the light switches were momentary (the low volt current only flowed for as long as the light switch was pressed) and this allowed for safer electrical wiring as well as less energy consumption. The 51300L is a 0-10V decorator dimmer switch that provides optimal dimming control for 0-10V compatible LED drivers, fluorescent ballast and HID ballast. Timers offer another way to control your lights. A dimmer switch , properly called a dimmer control, contains a solid-state circuit to allow changing the brightness by reducing the average voltage applied to the lamp. Be sure that your voltage is within the operating range of your fixtures. The dimmer switch is rated for the same voltage as the lighting application. When checking low voltage LED lights and systems, the inspector will check to see if the power supplies are accessible and Class 2 compliant. We ship out tons of low voltage switches and cover plates every day. This terminal plays no part in the action of the switch but, because there is available space, it is provided as an insulated terminal for joining other wires, if required (such as the neutral wires). It is strongly recommended that you consult a professional before attempting any lighting or wiring projects. This offers the advantage of permitting the building to continue to use the existing low-voltage wiring that is already in place between the transformers and switches. First, we’ll take a look at some basic components of a low voltage control system: transformers, switches and relays, and see a few simple control circuits we built for the greenhouse and our tracking solar array. But if the relays are burning up after replacement or other repairs to the system, check the low voltage transformer. Low-voltage transformers need an outlet that connects with your home’s electrical system. Any number of switches can control a single relay.
Low voltage light is warmer, sharper, and more natural resulting in better control by the surrounding components of the bulb, fixture, and controls. The cable used for low-voltage deck lighting is the same two-wire cable used for landscape lighting, which is like lamp cord or zip cord, only heavier gauge, more rugged, and able to handle sunlight exposure. To verify that a product is UL or ETL listed, check the product details in the lighting company’s catalog or website. Product Description LVS low voltage switch, Type: Momentary, Number of Buttons: 2, Pilot: No Pilot, Color: White. I’ve worked on countless low voltage landscape lighting installation projects that required careful planning and a lot of technical skill. If you have a GE low voltage light system and one of the lights in your home isn’t working, you’ll either need to replace the switch or the relay that’s connected to the switch. Electronic transformers are compact and lightweight. You have to have a special device — it’s called a driver, which is a kind of transformer that powers them. The easiest way to ensure that your light bulbs and dimmer controls are compatible is to check the lamp’s manufacturer spec sheet or dimmer compatibility sheet. Control hallway lights from two separate switches, convert standard outlets into USB charging stations, or set up extra lights around your home. Because of the danger of fire, it’s safer to limit the power to any circuit (fed from one transformer) to 300 watts. Low voltage electrical wiring was installed in some homes beginning in about 1946’s. Product Description LVS low voltage switch, Type: Latching, Number of Buttons: 2, Pilot: No Pilot, Color: White. Line-voltage lighting is typically more expensive to operate in the long run, but it’s less expensive to buy and easier to install. We get several calls every day from people who need to replace their broken low voltage light switches with currently manufactured parts. As there were 3 light switches in the room, I had the multimeter attached to the wires in the ceiling to see which switch (or switches) controlled the light. Low voltage lighting uses less electricity, saves you money, gives off less heat than traditional lighting, adds versatility for lighting in small spaces and is safer due to lower shock hazard. Hubbell Control Solutions’ Low Voltage Wall Switches are designed for virtually any area. For a standard application, connect the circuit breaker wire into hole 1 or 2 on the bottom of the relay. A simple electrical control system really only involves three things: a power source, a switch and a load. When you’re designing the lighting layout, place the light fixtures symmetrically so if you add additional fixtures, it will still look good. If sometimes when you operate the switch to control a light or receptacle or other device it works just fine, but at other times it fails to operate, giving difficulty in turning the light or receptacle “on” or “off” we could have a problem with the switch itself, or the problem may be with the relay that the switch controls. A successful low voltage outdoor lighting plan requires selecting the right fixtures, such as low voltage spotlights, then placing and wiring them correctly. Low-voltage systems are inherently safer. A light switch combined with a light socket is sometimes installed in basement or utility areas of homes. Also, low voltage wires cost significantly less than regular wires. If you have managed to restore power to the exterior outlet and the lights still won’t come on at night when the transformer is plugged in, then it’s very likely that there is an issue occurring with your lighting system. Although the initial cost is lower, operating costs are typically higher for line-voltage lights, unless they’re installed in low-use areas, in which case the operating cost difference will be negligible. My own experience would suspect a sticking relay, but a week output from the transformer can cause some relays to not work while others will. Use 10-gauge wire for the main lines from the transformer to where the lights begin, then switch to 12-gauge wire between the lights. Take a look at your old relay and pay attention to the number of wires coming out of the top. Learn more about low-voltage and line voltage lighting. In residential and light commercial lighting systems, the light switch directly controls the circuit feeding the lamps. Voltage good at switch: Locate and test relay. The National Electric Code (NEC) requires that low voltage power supplies and electrical wiring be Class 2 compliant. Figure 5. Probably the most common deck lighting, post-cap fixtures provide general lighting and decoration at once. The switch usually picks up the live for the switch at the light fixture. If the same breaker is used to power multiple rooms (for example, your dining room & kitchen), you’ll wire multiple relays together.
If a product purchased as a 3-way control needs to be used in a single-pole application, cap off one of the traveler wires with a wire connector. Switches are available in both momentary and latching versions and feature multiple button configurations making them the perfect switch solution for HCS’ low voltage occupancy sensors, daylighting controls and networked lighting control panels. Do not mix magnetic and electronic transformers or dimmers on the same circuit. Sierra Electric low voltage light switches, switchplates and relays were installed in mid-century homes built between 1940 and 1980 and were also known as “Square D” or Despard low voltage switches. Low voltage lighting is common in residential and commercial lighting, including display lighting, track lighting, and landscape lighting. This technology has been built into a series of dimmers specifically for electronic low-voltage (ELV) transformer loads. Product Description LVS low voltage switch, Type: Latching, Number of Buttons: 1, Pilot: No Pilot, Color: Light Almond. Now that you know how to prepare your low-voltage installation so that the LED lights, power supplies, connections and wiring are Class 2 compliant, you are ready for inspection. Easily buy replacement parts with confidence for your vintage Remcon, Sierra, Bryant, Pyramid, Touch Plate, and GE low voltage lighting systems at Kyle Switch Plates. Be careful not to place cable where it can be damaged by fasteners added later, and to avoid a short, be sure the power is off when working with low-voltage wiring. They have a very, very high input inpedance and will measure phantom voltage cause by capacitive coupling between open wires and other hot wires. The light is energized when both SPDT switches are in the up or down position. Flexibility – Low voltage switches can be wired in parallel to create 3-way switches wherever you need them for no addition cost for new or specialized switches. Use magnetic low voltage dimmers with magnetic transformers and electronic low voltage dimmers with electronic transformers. The light produced by low-voltage bulbs is sharper and looks more natural than higher voltage bulbs, which produce warm light that’s more diffused. Conceal the LED or turn the lights off and LED is ON. No relays, just circuitry of sensor resistors, chips, and capacitors. Installing low-voltage outdoor lighting is a big-impact DIY project. Product Description LVS low voltage switch, Type: Momentary, Number of Buttons: 1, Pilot: No Pilot, Color: Gray, USA transformed. Perhaps the most obvious way to light stairs is with fixtures recessed into the risers. While it’s difficult to focus the beam of a high-voltage bulb that tends to scatter light, low-voltage bulbs offer a high degree of optical control using just the bulb’s reflector. Additionally, there are a wide variety of low-voltage outdoor fixtures available. Switches typically remain in service for many decades, often being changed only when a portion of a house is rewired. The low voltage WiFi switch is a WiFi based wireless switch that can connect to a wide range of appliances. Transformer Voltage Good: Wiring damaged or stuck switch on the circuit. No. 3-way dimmers may only be located in either of the 3-way switch positions. In protected planting beds, the low-voltage wire can simply be covered by mulch or soil. Lollipop circuits work great when the transformer is 75 feet to 100 feet from the first of a group of fixtures. One being the common wire and the other being the switch wire, and because of our single coil relay, the same button is used to turn the relay on and off. REIGN dimmers are low voltage dimmer switches that operate only with our standard 12V or 24V DC Constant Voltage Drivers and plug-in adapters. If the client wants more light (and I usually encourage them to live with the layout for a week before we make changes), you can add fixtures so that every post has one. Does what it is supposed to do, works well for dimming low voltage under cabinet LED lighting run through a transformer. In addition, each momentary switch could be wired to perform the same function as a single pole switch, 3-way switch or 4-way switch, so one could operate a single light from multiple remote locations without complicated wiring. Product Description LVS low voltage switch, Type: Latching, Number of Buttons: 2, Pilot: No Pilot, Color: Gray. The switching relays made by these manufacturers work differently from those designed and sold today by Touch-Plate lighting. For low voltage replacement options, General Electric (GE) and Touch-Plate actively manufacture updated switches, wall switch plates and relays for use in their older low voltage lighting systems. Dimmer switches should be installed inside, though this complicates matters somewhat. If your home is currently wired with Touch Plate, you’ll find replacement Touch Plate relays, transverters, switch units and cover plates available on our site.
Product Description LVS low voltage switch, Type: Latching, Number of Buttons: 2, Pilot: No Pilot, Color: Light Almond. LED fixtures cost a lot more than similar ones that use incandescent lamps, and the variety of styles of fixtures with LED light sources is pretty limited. Touch-Plate® switches only have two wires. Each button provides a momentary contact that is intended for use with compatible low voltage relay panels or similar lighting control panels or devices. On decks requiring multiple circuits and transformers, using loops from the transformers to the more distant circuits can eat up a lot of cable. Think of Relays as electrically powered switches, that are often employed by control circuits to energize larger loads, or otherwise isolate circuits. The low-voltage electrical wiring system popularized in the United States by GE® and Remcon permits the use of less-costly and easier-to-install wiring between the relays and the switches in the home. Used this switch to control LED tape lights that required two drivers. Still, larger systems (20 or more fixtures) have larger voltage drops so it’s good to equalize voltage whenever possible. Regular incandescent dimmers often contain a small amount of DC voltage, which is harmless to a regular incandescent load but may damage magnetic transformers. Use plastic wire clips with stainless steel nails to secure the landscape lighting wire to the tree every 3 ft. Two light switches in one box. Single-Pole Dimmers provide control from one location. At least one supplier continues to design, sell, and service low-voltage home wiring systems: Touch-Plate Lighting Controls, in Fort Wayne IN. Some of the suggestions and opinions in this article are quoted from or paraphrase advice offered by that company. First, find a ground-fault circuit interrupter (GFCI) outlet to act as the connection point between your home and the outdoor lights. Lay everything out, hook up your lights, test your voltage, and look at your results at night before burying the lines. Product Description LVS low voltage switch, Type: Latching, Number of Buttons: 4, Pilot: No Pilot, Color: Light Almond. LVSW-100 Series Low Voltage Switches are lighting control devices that use conventional point-to-point low voltage wiring for control of single or multiple loads. Newer Touch-Plate low voltage switches, for example, will work in older General Electric (GE), Remcon and Bryant low voltage systems, so they are a great compatible replacement option for many. A switch of basically the same design is also used on Australian power outlet wall-plates. Nowhere in the product description did it mention a relay control. If you can turn your outdoor lights on and off with a light switch then you have two options. The relays, in turn, are connected to manual switches with low-voltage wires. Dimmers for magnetic low-voltage transformers use a technology known as standard phase control or leading edge,” whereas dimmers for electronic low-voltage transformers use reverse phase control or trailing edge.” Standard phase control is for use with either inductive (MLV transformers, fans) or resistive (incandescent) loads. Each of those lights can be automated with the right smart products. 3. Certain MLV transformers may not be compatible with all Lutron® dimmers. Lutron® ELV dimmers are designed specifically for the special electrical requirements of electronic transformers. MLV transformers with built-in input chokes or debuzzing coils” may not be compatible with certain microprocessor-based dimmers. I see 3 wires twisted, so power in, power out, and power to switch. Once you know your transformer will work with your light fixtures, look for other convenience features. The relay are more common to go out than switches but both fail. Low voltage fixtures consume the same amount of power as other lights, but they often produce more brilliant beams. Many original GE® or Remcon® low voltage lighting systems are still in use today. Each lighting load to be controlled is wired through a relay. However, the higher shock and electrocution hazards of line voltage, combined with fewer fixture choices, make me favor low-voltage systems for smaller projects. First, for Touch-Plate® installations, If the relay you are replacing has two wires coming out of the cylinder the relay is a 1550 series and it can be replaced by the Touch-Plate® 2500-B. Depending on the application, transformers can ‘step up’ the incoming voltage (microwaves, arc welders) or ‘step-down’ transformers such as those on the telephone pole in your neighborhood. To minimize voltage drop, I get the power to the first fixture on a 10-gauge cable, and from there create a loop of 12-gauge cable in the area where the fixtures are located. If none of your lights are coming on, the best place to start is the transformer (the metal box all the lights are hooked up to).
