Here is a photo of the switch, the live is switched through the common and NO.
It is mounted ontop of 1 transformer and the black part you can see to the left of the photo moves back and forth when the transformers are powered. i think this part holds the micro switch closed in operation and if this were to move away from where it should be the switch will open cutting the power.
I need to know if this can be purchased or if there is a direct replacement.
thanks
