I'm trying to work out the current wiring on a 2-gang switch. The switch is 2-gang and 2-way but is wired as 1-way on both switches.
The are 3 x 2 core and earth cables connected to the switch. The black wires of all three are connected to each other but nothing else, the same with the earth.
The red cables go one to each of the L1 terminals on the switches, and one connected accross the COM of both switches.
How can I identify which of these does what so that I can add a second (2-way timer) switch to on of the lights?
I'm epuipped with a multi meter if that helps...
