Can you put a dimmer switch on a 3 way switch?

Why does my 3-way dimmer switch not work?

What is L1 and L2 on a dimmer switch?

The wires from your old switch can be connected either way round to the “C” and “L1” terminals of the dimmerswitch. If you are using a push-on/push-off dimmerswitch there is a spare terminal (L2) that you will not need to use for a 1-way circuit.

Do dimmers need a neutral?

Since most Insteon-compatible wall switches and dimmers require a neutral wire connection to operate, you need to know if you have one of these in place. A neutral wire is a type of wire in which carries currents back to the source of power and or regular voltage.
