Hi, I was wondering if anyone can help me, I'm trying to work out which two of these three microswitch tabs to use. I have a Hotpoint Hug52 oven and the grill won't stay lit. I checked the thermocouple and it looked in a poor state so I have installed a new one. I took a photo of the wires on this switch but like a dingbat I accidentally deleted it. Basically it has one wire coming from the thermocouple, and one from the front panel controls. The switch is operated by the oven door closing, as the door should not be shut when the grill is in operation. Thanks
