Unbelievable Three Way And Four Way Switches
These illustrations show code compliant wire.
Three way and four way switches. This tutorial will show you how to wire 3 way and 4 way switch circuits. A 4 way switch has two positions. Some have the light between the switches while some have the light at the end.
Several example circuits using two switches to control a light. For more than two switches one or more 4 way switches are added between the 3 way switches. The tutorial uses the powerful electrical design and simulate software called const.
4 way switches an animation. Three way and four way switches how they work. This one minute animated tutorial is my clearest presentation of 3 and 4 way switches in action.
It can also help to diagnose a three way switch that does not work because someone. Slide your mouse over the image to see the switch change state if you have javascript enabled in your browser.
