Smart Two Way Switch Installation
The white wires are wire nutted together so they can continue the circuit.
Two way switch installation. It is a standard single pole switch with three terminals. The three terminals are usually named com l1 and l2 but sometimes com 1 way and 2 way are also used. Basically connecting a switch either end of a room to control the same lights.
However you can set up specialized two way dimmers using a master and slave switch. Connect the white wire with the white wire the black wire with the black wire and either splice the red wire with the black wire or attach it to the black wire s source. Step by step.
Before proceeding an important component called a two way light switch is the main element of the 2 way switching irrespective of the type of wiring used. I believe this is called a three way switching circuit in some. The two way switch will have corresponding wires or screws.
Notice the black wire is the only wire that we are controlling through the 2 way switch. In one position the com and l1 are connected while in the second position the com and l2 are connected. Any electrician will tell you that this will not work for a regular double switch three way circuit.
