Is it normal for an immersion heater switch to flash inside when it is switched on and off? I have checked the terminals for tightness and they seem ok.
I am thinking of replacing the switch with a new one and have been told that I should replace it with a switched spur instead of a 20amp switch which is currently used. is this advice correct?
thanks in advance.
