Abstract

A thermostat including a housing assembly, a snap-acting thermally responsive actuator, and a control switch is disclosed having a switch operating arrangement coacting with the switch and the actuator. The switch operating arrangement includes a lever structure hinted to the thermostat housing assembly for transmitting motion between the switch and the actuator by pivoting about the hinge. Heat transfer to the hinge is minimized so that movement of the lever is not impeded by the effects of heat on the hinge. The lever structure slidably engages the switch during movement about the hinge resulting in gradual wearing away of the switch engaging lever portion which compensates for normally occurring switch contact erosion.
