Touchplate Low Voltage Lighting FAQ


Q. What is the difference between the different Touch Plate low voltage series? Genesis, Classic, 5000, Ultra?

A. The only difference between the different Touch Plate low voltage series is the appearance. Otherwise all of the switch units function the same, as 2-wire 28 volt low voltage momentary switches. If your home is wired for Touch Plate, you can choose between the Genesis series, 5000 series, Classic series , Mystique series, and Ultra series. Note that the Ultra switches fit into standard Decora rocker switch plates which makes them very versatile.

Q. I have a crooked wall box. Will all the switches allow adjustment?

Genesis switch controls screw directly into the wall box so if the box is crooked, you will not be able to adjust the position. All other switch series have larger screw slots to allow for some adjustment.

Q. Are the Touch-Plate switches momentary?

A. Yes, all Touch-Plate switch units feature momentary switches. This means that you press in the switch, it makes a momentary contact to the relay, then returns to center. The button will not remain pushed in.

Q. Can the Touch-Plate switches we used as a doorbell?

As long as the doorbell is low voltage and 2-wire/momentary, Touchplate wall switches can work fine. Typically a doorbell is separate and isn't connected to the low voltage system. So this means it wouldn't be different for a 3-wire system or a 2-wire. A doorbell switch typically goes right to a doorbell transformer and doesn't connect to anything else. A momentary switch (SPST) is all that is needed.

Q. Can the Touch-Plate switches we used to control a garbage disposal in a 2-wire low voltage system?

A garbage disposal can be controlled by a relay. Just like a light switch, the disposal still operates on AC, but the switch/control is on DC. We have had many customers in older homes who had their disposals on a relay. 

Q. Can I use Touchplate low voltage switches with regular voltage light bulbs?

A. Yes, you can use Touch Plate low voltage switches with regular voltage incandescent light bulbs. The bulb type doesn't matter as long as you don't go over the voltage limit on the relays which are usually 20A.

Q. Can I use Touchplate low voltage switches with LED or fluorescent light bulbs?

A. Yes, you can use Touch Plate low voltage switches with non-dimmable LED and fluorescent light bulbs as long as you don't exceed the relay's load which is typically 20 amps. If you want to use dimmable bulbs you will need to upgrade to a new Touch-Plate ZoneZ Dimming panel.

Q. Can Touch-Plate low voltage switches be used outdoors?

A. While Touch-plate switches are not moisture resistant, if you are using them in damp areas such as outdoors or in pool areas, you would want to use weatherproof covers with them. We recommend the Touch-Plate Ultra switches because they fit into standard decor rocker weatherproof covers.

Q. Can I use a 2-wire Touch Plate low voltage switch unit to replace my 3-wire low voltage switch, such as GE, Bryant or Remcon?

A. Yes, you can use a 2-wire Touch Plate switch unit to replace your 3-wire low voltage switch unit. You will need to split off the common wire, have 1 split go to the ON switch and 1 split go to the OFF switch. You will then have 1 button be your ON and a separate button be your OFF. You will no longer be able to have the same switch function as your ON and OFF. Because of this you will need to double the amount of buttons per lighting location. For example, if you have 2 GE switches in a switch plate, you will need to get a 4 button Touch Plate switch unit to replace it. It is pretty basic wiring. We offer a 3-wire to 2-wire conversion wiring guide free with the purchase of any Touch Plate switch unit. Be sure to add it to your cart and we will include it in your order. 

Q. If I replace my Remcon or GE switches with Touchplate switches, do I have to use Touch-Plate relays with them?

A. No, you must always use remote control relays from the same type of system. Even if you swap out the type of switches you use in your system, you must continue to use the correct relays for it - Touchplate relays in a Touch-Plate system, Remcon relays in a Remcon system, GE relays in General Electric (or the similar type Bryant and Sierra) systems, etc.

Q. Can a Touchplate switch be wired as a 3-way or 4-way switch?

A. Yes, it can. The switch is wired in parallel to the relay it is controlling. So for that reason, you could have an unlimited number of switches controlling the same light. The relay just responds when receiving a signal from whatever switch.

Q. My old Touchplate 1550A relay was 14 VDC. Can this be replaced with the new 3000 relays?

Yes. For a period of time in the past Touch-Plate was marking their relays with the lower voltage, even though they really had a higher voltage. Some were labeled as 12 VDC; others 14 VDC. But all Touch plate systems have always worked with 28 VDC transformers and transverters. To confirm this with your system, simply check the output voltage on your unit.

You may safely use a 3000 relay to replace a Touch Plate relay marked as 12V or 14V, and may use a new TPS-0120 transformer with either the new or the old relays.

Q. My wires were soldered to the bracket on my vintage low voltage switches. How do I connect the wires on the new Touch-Plate switches?

The new switches have stripped leads so you may use wire nuts to connect them to the in-wall wiring once you cut off the old switches.

Q. My pilot lights are stuck on. How do I fix them?

The pilot transformers are wired in with the relay and will change state (ON and OFF) with the relay. The pilot transformer only gets power when the relay is in the ON position. If the pilot light is remaining on, the relay has failed in the ON position and is no longer switching. Replacing the relay should solve the problem.

Q. I installed a new 3000 relay and switch but my lights started to flicker after a few days. What would cause this?

A. Flickering is almost always caused by a weakening power supply. The relay is getting insufficient power and it cannot hold the next position when triggered. Test the transverter first. While it's more common to have failures with 2-3 relays when the power supply starts to weaken, sometimes a single relay can start experiencing issues. As time goes on and the unit weakens, more will start to become intermittent/erratic as well. If you check the transverter voltage and it is normal, then next check the actual fixture itself and the wire connections on the line voltage side (both at the fixture and at the relay). There may be a loose wire which is causing the light to flicker when the power is lost. It's very unlikely that it is a relay problem. A relay does not fail in this manner. It will either not work at all or work intermittently, but it will not cause the light to flicker.
