Single terminal snap acting thermal switch

摘要

An externally threaded grounded metal housing mounting a snap acting disc at a closed end is shown to receive an electrically insulative body mounting an "L" shaped movable contact member having an upstanding leg biased into contact with the internal surface of the housing wall and a laterally extending movable contact leg with a tongue cut and bent out from the leg and engageable with the snap acting disc. A terminal is pushed into a slot of the body and mounts at its free distal end a stationary contact. The mounting surface for the movable contact member is skewed relative to the lid terminal slot in order to obtain a longer effective movable contact arm.
