Chris, Glyn said he earthed the switch via a milliameter and 10ma was drawn and all was well except the other switches still showed leakage. Hence my saying that if 3 of the switch plates were connected to earth and leaking 10ma each then that would be the trip current of a domestic RCD.

Very difficult to diagnose without seeing the switches and the situation though but whatever, if they are giving a nip then it needs to be resolved.
