Abstract:

A thermostatic switch of low profile comprises a can with a stationary contact attached to the bottom of the can. A movable contact affixed to the end of a snap-acting bimetal member is positioned to make or break contact with the stationary contact. A flat heater has one end secured to a dimpled portion of a can lid and has its other end resting against the lid in insulated relation to the lid to extend generally parallel to the lid. This other end of the heater is also welded to the bimetallic member. The can and lids incorporate terminals. A gasket insulates the lid from the can and is positioned to a positive stop to a lead when inserting the lead into the lid terminal.
