Abstract
An electrical switch comprising a moveable contact member resiliently biased to have an electrical contact portion thereof urged into spaced relationship with an electrical contact portion of a fixed member to open the switch and to have another protruding portion thereof disposed for pressure engagement with a cam surface of a reciprocally moveable actuator to urge the electrical contact portions of the contact member into electrical engagement with one another for closing the switch, and a dielectric barrier member carried on the actuator in predetermined positional relationship with the cam surface for movement out of a position between the electrical contact portions, before the switch is closed, to permit the electrical engagement of the contact portions with one another and for movement back into the position between the electrical contact portions, after the switch is open, to prevent the undesired effects of contact bounce.
