Miniaturized snap acting thermostatic switch

Claim 1

A thermostatic switch comprising: a. a generally cup-shaped housing of electrically insulating material having an open end and a closed end with sidewalls depending therefrom and defining a cavity therein; b. the end wall of the housing provided with an aperture train; c. a relatively stiff, generally bicornuous member located in the aperture and having two legs in clamping engagement with the end wall, one leg of the member being elongated and extending substantially across the cavity; d. a stationary contact mounted on the distal end portion of the member; e. a second aperture provided in the end wall and receiving therein an adjustable member adapted to engage the elongated leg and bias the leg toward the open end of the housing; f. a metallic cover enclosing the cavity in the housing; g. a snap acting thermostatic element having two ends and a nondevelopable portion, the element cantilever mounted by interposing one end between the housing and the cover; h. a movable contact mounted on the distal end portion of the thermostatic element and adapted to engage and disengage the stationary contact; i. an outwardly extending annular flange provided on the distal portion of the housing sidewalls; j. the outer peripheral portion of the cover turned radially inwardly about the flange of the housing to clamp the cover to the housing; and k. a terminal leg extending from the cover.
