Abstract
An electrical switch assembly including two separate, temperature-dependent electrical switches, one of the electrical switches being substantially mechanically acting and the second of the electrical switches being a non-mechanical, solid-state switch. The mechanical switch may be a bimetallic switch of various configurations or may consist of a snap or toggle switch actuated by the expansion of a suitable fluid, for example a wax mixture. The solid-state switch element may be a resistive element which inhibits the electrical conduction upon the occurrence of elevated or lowered temperature, depending on the type of material used. Various embodiments of the mechanical portion of the switch assembly are presented.
