Abstract
A switch for operating a heating element of a cooking appliance includes a first contact electrically connected with the heating element, a second contact electrically connected with a power source. A bimetal strip is configured to electrically connect and disconnect the first and second contacts. The switch further includes a rotatable cam member having a cam surface for operative engagement with a cam follower. The cam surface has a profile dimension that is at least partially variable about the rotational axis of the cam member and is configured to cause displacement of the cam follower as a function of its rotational orientation to thereby adjust an operating temperature of the heating element. The cam surface is configured such that the operating temperature can be adjusted up to but not beyond a predetermined maximum temperature via rotation of the cam member. Circuits incorporating such a switch also are disclosed.
