Light Wiring Diagrams

2 gang 2 way light switch

This switch arrangement is basically two two way switches on a single face plate.

Some brands of light switch may have slightly different labeling on the terminals (such as C L1 L2 or even L1 L2 and L3).

Each of the gangs (or switches) above in Fig 2 (of which there are two) work like this (Fig 3): In position 1 (when the switch is down or ‘on’), COM and L1 are connected together (just like the one way switch). In position 2 (when the switch is up or ‘off’), COM and L2 are connected together.

There are no connections between the two gangs in Fig 2. Each gang is a single discreet switch.

Just to be different:)

The terminals on your switch may be a little different to those shown above but rest assured they function just as described above but the terminal pins are in different positions. You may see the following:
