Thanks Spudd for your instructions. I took the lock switch out, metered the switch, it was not working. There is a metal U shaped bar that holds the switch together, this was stiff to remove but a bit of lubrication got it out. You can then remove the old microswitch.
I found a similar one on ebay for £3ish, (or try Maplins) soldered it to the wires and located it with a bit of silicon sealer (like you would use to seal a sink) making sure that the activation bar operates the switch. Leave it overnight for the sealant to set. Test it before it gets installed again.
Make sure you buy a switch with a decent 12v DC load (mine is 5A) and if it is a three pole switch you will need to make sure you use the common pole and the pole that closes when the switch is operated i.e. it makes a circuit.
Reassembled the switch assembly and the door, works a treat.
