Switch cable too short now Ask questions and find answers to many subjects relating to electrics and electrical work

Attempting to tackle what I thought should be straightforward, changing white standard light switch to a fancier one which fits flush to wall surface. Unfortunately the recessed box was not deep enough and the wires must have been pressed on to the back of the box when screwing the plate on, and the screw on the backplate has cut through the cover on one of the wires. The circuit tripped as soon as I reconnected the supply. the wire was too brittle now to do anything with but is now too short to connect properly to the connections. Is the only alternative to cut through the platerboard to remove the wire behind to fit a new one (it is obviously clipped to the breeze blocks behind the plasterboard)? Cheers

Cables can be joined if this needs to be done in an inaccessible place it needs to be done with crimp connectors and covered with shrink sleeve. And the crimping should be done with a good set of crimp pliers which crimp to a pre-set amount not the cheap DIY type. As with any electrical work if you are unsure get an electrician to do the work.
