Im posting here in case an electrician can answer my question... I was cleaning my light switch in with cif as they are badly stained and obviously the sponge was damp and some water got into the switch ( yeah i know stupid thing to do but its done...) and i got a shock. clearly only a small one as i can still do stuff !! however will the switch just dry out and then be OK ?? and is there a way to test if it is OK without sticking my finger on it ??
