ABSTRACT:
A time delay relay (TDR) is formed by capturing a thermostatic switch between identical shells of an outer housing and suspending the switch in a switch cavity to minimize heat loss to the outer housing. The shells are bonded together to form a unitary housing member. Heater terminal members are captured in identical grooves formed in the housing shells with the terminals projecting from either the top or bottom of the TDR. An alternate embodiment includes a manual reset mechanism also captured between the housing shells.
