Headlight dimmers work in a different way. Some dimmer switches are set on a 3 way switch.
How Three Way Light Switches Work
How does a dimmer switch work diagram. Find out what this clever switch does with electrical current. A dimmer cant control too many lights or it will surpass its maximum wattage. A 3 way dimmer switch is very similar to a regular 3 way toggle switch except for the electronic unit which performs the actual dimming function. You can put your lights on a dimmer switch in no time. More about wiring switches and dimmer switches. Lets take a closer look at how a dimmer switch works.

Overlamping a dimmer switch is the most common reason a dimmer switch fails. Like a transistor a triac is made up of different layers of semiconductor material. When the normal lights are turned on the dimmer sends a small current to an electric switch called a relay. A triac is a small semiconductor device similar to a diode or transistor. The central element in this switching circuit is a triode alternating current switch or triac.
But if youre replacing a three way switch with a three way dimmer label the common wire itll be labeled on the old switch when you remove the old switch so you can connect it to the common terminal on the dimmer. This turn on value is based on the position of the dimmer switchs knob or sliderif the dimmer is turned to a brighter setting it will switch on very quickly after cutting off. 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. This current closes the switch turning on the normal headlights. This means that the lights can be turned on and off from the dimmer switch as well as another light switch.
