Dimmer Switch Circuit Diagram. From the dimmer 3 wire cable runs to the other switch and 2 wire cable runs to the light fixture. The central element in this switching circuit is a triode alternating current switch or triac.
Standard single pole dimmers and three way dimmers. From the dimmer 3 wire cable runs to the other switch and 2 wire cable runs to the light fixture. Like a transistor a triac is made up of different layers of semiconductor material.
Traveler wires are interchangeable on each switch.
The dimmer switch will have stranded wires that must be sliced to the solid cable wiring in a pigtail fashion. The black line wire connects to the common terminal of the 3 way dimmer. In the last section we saw that a dimmer switch rapidly turns a light circuit on and off to reduce the energy flowing to a light switch. With a standard single pole dimmer a single switch controls the.
