2 Way Switch Wiring Diagram Old Colour. 16 Apr 2014 Messages. The diagrams show plastic switches with the earth connection to the backbox or patress.
Any number of intermediate crossover switches may be added to give three or more switching positions. Discussion in Electrics UK started by peterh1967a 12 Sep 2014. Basically connecting a switch either end of a room to control the same lights.

The three terminals are usually named COM L1 and L2 but sometimes COM 1 Way and 2 Way are also used. It is a standard single pole switch with three terminals. 2 way switching means having two or more switches in different locations to control one lamp. 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.
