Hi we are trying to change a one gang two way light switch. The one we have taken off has no com, two L1s and two L2s. The two red wires are joined together with an isolator, there is a blue in L1, blue in L2, yellow in the other L1 and yellow in the other L2.
The new switch has a com and one L1 and one L2. Is it the wrong switch or can it be wired up with what we have?
The switch is one of 3 which operate one light.
