Light Dimmer Switch Diagram. Dimmer switches have come a long way since 1961 when joel spira invented the first electronic dimmer switch. A device like this should only be used with an incandescent light fixture.
Dimmer switches have come a long way since 1961 when joel spira invented the first electronic dimmer switch. The central element in this switching circuit is a triode alternating current switch or triac. Traveler wires are interchangeable on each switch.
Light switches once a simple decision are now a home improvement category boasting a number of designs and functions.
Like a transistor a triac is made up of different layers of semiconductor material. Standard single pole dimmers and three way dimmers. 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. Dimmer switches have come a long way since 1961 when joel spira invented the first electronic dimmer switch.
