2 way switch 3 wire.
So now that you have a basic concept of wiring a 2 way switch let s look at the following 2 way switch diagrams to see which type of circuit scenario you have.
With a pair of 3 way switches either can make or break the connection that completes the circuit to the light.
This should give you a good basic understanding how the 2 way switch circuit works and will help you in adding or changing a 2 way switch.
You will see that there is a hot wire that is then spliced through a switch and that then goes to the hot terminal of the light.
In this diagram two 3 way switches control a wall receptacle outlet that may be used to control a lamp from two entrances to a room.
The red wire from the feed cable is connected to the top terminal the red wire going to.

The power source comes from the fixture and then connects to the power terminal.
A one way light switch is quite easy to wire up.
Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram.
