ABSTRACT:
A switch comprises a housing with first and second spaced apart stop members with at least one of them being an electrical contact. A current carrying contact is mounted in the housing so as to project outwardly for connection to an electrical circuit and to extend upwardly inside a cavity of the housing. A two armed swivel member is pivoted over the current carrying contact and a movable contact portion is pivoted on the one arm of the swivel and it has an outer end which is oriented between the two stop members for engagement with a selective one in each operative position. The opposite arm of the swivel member is engaged by a lever which is pivoted in the housing and which is movable by a push button to actuate the switch. The spring is engaged with the movable contact and an extension of the lever member so that in an actuated position it is biased by the spring into engagement with one of the stop members. Displacement of the lever member by either a push button or a rotary actuator causes the movement of the spring through the pivot position of the movable contact and then a snapping of the switch into a second position against the opposite one of the stop members or contacts.
