#3 WAY SWITCH ONE SWITCH HAS TO BE ON SERIES#
It takes a pair of three-way switches working together to route electricity on or off from both locations.Ī 3 way dimmer allows you to turn a light or series of lights on and off as well as control the light output. A three-way switch by itself is not enough to control a light. To make the circuit function properly you need two locations both using a three-way switch. One is a common wire which has a current while the other two carry the common current to two lines. That’s why a three-way switch has three screws. Whenever two switches control a single light or a group of lights, you need a three-way dimmer.Ī three-way dimmer doesn’t just turn electricity on/off and dim the light, it also switches the current from one line to another. This lets you dim the light from one location and turn the lights on and off from another. You’ll need a three-way dimmer and a three-way switch to make the circuit function properly. With a three-way dimmer, you can control the same light with two switches from opposite ends of a room. With a standard single-pole dimmer, a single switch controls the light. Dimmers come in two basic designs: standard single-pole dimmers and three-way dimmers. Yes, a dimmer can be used on a 3 way switch.
