Duel element switch operation

The dual element switch on a smooth top range is no different in operation than that of a single element switch other than it operates both the main burner and the middle or bridge burner.
Inside the switch is a cam and a bimetal. The cam presses the contacts together for heat and the bi-metal devides the contacts when the heat builds acording to dial setting. Full on the bi-metal has no effect and the element stays on all the time. Any other setting varries between the distance of the contacts as dictated by the cam mounted on the center post. It ain't rocket science, this system has been around for decades.
