Which Switch

[bolo 2]

Our bathroom has 2 switches on the same box, one for the light and the other for the extractor fan. The light switch still operates the light but has lost its springiness and its clicks. Because of my location,I have to order the replacement online but don’t ready know what the switch is called. Can anyone help?

If you order 2 gang 2 way you will be safe.

A picture always helps though

What he said

Make sure you mark your wires before you disconnect, its easy to get the reds mixed up.
Also, note that the new switch may not have the same terminal markings as the old one. Happy to assist if you aren't sure.

This one Ok?

 

[bolo 2]

Negatives are wired together in a terminal block in the switch box.

 

[SFK]

Yes that one is okay.

Wiring based on the new terminal markings is as follows [Edited]:
OLD >>> NEW
'A/B'COM = COM
B1 = L1
B2 = L2

As Taylor says, make sure you mark the wires before you disconnect them.

If after you have wired the new switches in, and one of the switches is operating upside down compared to the to the other, then if the wire is in L1 move it to L2, if the wire is in L2 move it to L1.

Negatives are wired together in a terminal block in the switch box.

Fair enough, but, for the record they are called 'neutrals', not 'negatives' (something which only exists with DC).

Kind Regards, John

Wiring based on the new terminal markings is as follows:
OLD >>> NEW
ACCV = COM

The markings on the old switch actually read:
‘A‘ COM= COM
‘B’ COM= COM
and I suppose that’s the same thing really.Will be making the swap in an hour or so and wonder if any of the guys who helped will be around if things go wrong?

Yes ,all waiting for you to succeed

 

[bolo 2]

One last question. Of the 2 wires coming from the top left Common, one is a loop into the bottom right Common. I take it that I wire the new switch in the same way.

 

[terryplumb]

Yes the red wire going into com is the permanent live ,the small piece is a bridge ,taking permanent live to the other gang ( switch)
