Abstract
Electrical switches are disclosed which are of the type having a slidable contactor which is movable along a predetermined path in a casing. The contactor is engageable with a plurality of electrical contacts disposed along said path. To provide for selective engagement between the contactor and the contacts, at least one fixed cam element is provided along the path of the contactor and is engageable by one or more follower elements on the contactor to lift the contactor away from at least one of said contacts in at least one position of said contactor. In certain embodiments, the contactor is preferably formed with a slot which is adapted to receive an insulating projection on the carriage, so that the contactor is caused to move in a precise manner along with the carriage.
