Light Dimmer Switch Diagram. Dimmers come in two basic wiring configurations. But you won t be able to dim the lights from every switch location unless you buy a set of special dimmers with advanced electronics and install one at each switch location.
A triac is a small semiconductor device similar to a diode or transistor. A rheostat or dimmer makes it possible to vary the current flowing to a light fixture thereby varying the intensity of the light. Care should be taken in selecting your dimmer switch.

The dimmer switch has 2 black wires and one red. The dimmer switch will have stranded wires that must be sliced to the solid cable wiring in a pigtail fashion. A device like this should only be used with an incandescent light fixture. The wall switch has two whites together caped two blacks in the switch and then the green.
