FIELD: electrical engineering. SUBSTANCE: thermostatic switch has soldered up unit consisting of heat conducting element, thermosensitive substance and bushing arranged on turnable axle of thermosensitive substance. Fitted on bushing are limiting projection and movable part of contact system. Bushing takes up efforts of disconnecting spring. In case of temperature rise viscosity of thermosensitive substance is decreased or substance melts, and bushing is turned under effort of disconnecting spring, thus opening the circuit.
