  • Patent number: 4609795
    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.
    Type: Grant

  • Patent number: 4073563
    Abstract: The invention provides a modular structure for electrical connections with an integral molded frame wherein a forward portion of the frame has holes to receive electrical conductors and a rearward portion carries one or more electrical contact assemblies, said frame being adapted to fit into the rear of a panel, with or without elimination of screws previously used for panel mounting, and with the elimination of separate sleeves that have to be brazed on the jack frame, thereby reducing manual operations and simplifying manufacture while providing versatile modular components especially useful in telephone switchboards and apparatus, multiplex and microwave systems, television and broadcast equipment and other control panel applications where small size and reliability are prime engineering and operating parameters. Other features are the provision of a new extruded panel, and the provision of a special type of jack sleeve made from a wrapped up stamping.
