Hi. I want to replace a faulty switch on a heater circuit but need some advice - photo of circuit attached. Heater has 2 simple on/off switches - one turns a 1Kw circuit of heaters on, the other a 1.5kw circuit of heaters on, both can be on separately or together to give a possible 3 levels of heat. There is also a variable thermostat to change the output setting. One of the switches no longer works but the replacement switch I have has only 2 pins on it, the existing switches have 3. I'm wondering if the live wires on the first switch in the diagram (pins 1 and 2) can be put on one pin rather than 2 as present or if that is just a really bad idea!? Are the live wires going to be always connected between pins 1 and 2 and the on/off switch makes the circuit between live and blue wires, in which case combining the live wires on one pin would presumably be ok? Or not!? Advice welcome please.
