Wiring A Two Way Light Switch With Double Switch. A double light switch is used to turn two separate light sources in one area on and off. For example, you might want to turn on a bathroom light separately from the ceiling fan.
First we need to put down the safety device and strip all the wires, being careful that they don't get in contact. In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load (often, but not always, lighting) from more than one location. A four way switch takes in two power wires, and sends two out.

More than two switches add additional "four way" switches between the first two.
All the previous switches I changed out were straight forward. Position the switch in the electrical box so that the ON position is facing up toward the ceiling. Find solutions to your wiring diagram double light switch question.
