Light switch

[figo7]

Hi guys

I've just had a look at my mums light switch as she was saying the light is not coming on.

It looks like a black wire has slipped out from its connection but I'm unsure where it goes?

The wiring setup is for a single light switch:

1) 1 single black wire.
2) 1 red and 1 black wire.

a) the single black wire (1) and red wire from (2) are screwed into one connection.

The black wire from (2) is loose?

Any ideas on where it would go would be appreciated..

Your switch is likely to be labeled
com/L
L1/one way
L2/two way

I would expect the pair to be in com then the loose connection to L1/one way
