ABSTRACT:
An electrical switch construction having a housing carrying a pair of spaced contact stops and a snap switch blade having a contact portion for being snapped between the stops when the blade is moved over center by an actuator spring member that is movable relative to the housing by an actuator plunger. The actuator spring member has opposed ends respectively and operatively interconnected to the housing and to the blade and being under tension between the ends thereof so as to have a resultant spring force normally tending to move the actuator spring member toward the plunger and thereby the switch blade toward one of the contact stops. The actuator spring member comprises a one-piece substantially L-shaped leaf spring member separate from the blade and having two legs respectively defining the opposed ends thereof, one of the legs being pivotally mounted to the housing to operatively interconnect that one leg to the housing.
