Our snapdisc switches work by using a bimetal disc. The bimetal disc in the switch reacts to heat, and opens or closes a set of contacts based on what the ambient temperature is. This is works because the different metals in the disc react to heat in different ways, which causes the disc to bend. In the case of a generator, the disc pushes the contacts in the switch open, which cuts off power to the generator. Once the generator cools down, the contacts are able to close again, allowing the generator to be powered back on.
