  • Patent number: 4400598
    Abstract: A slider switch mechanism especially adapted for use on the steering column of an automotive vehicle for use as a speed control mechanism. The switch mechanism uses a slider constrained to translatory motion within guides of an enclosing housing. The slider is first assembled to a support member and the resulting assembly is fitted into and locked to the enclosing housing. The slider bears a compression spring which is held between axially spaced posts of a support member. The support member is fitted into an opening in one end of the housing and is advanced until a resilient locking member snaps into a cutout in the adjacent wall of the housing. When the support member is fully advanced into the housing, mating holders of the support member and housing are joined to lock the slider assembly into the housing. The slider may then be translated as necessary within the housing cavity, as desired.

  • Patent number: 4393281
    Abstract: A dual inline package switch assembly containing one or more separate electrical switches is disclosed which comprises an insulating housing consisting of a base and a cover to provide an interior space. The cover has at least one slit extending into the interior space in alignment with the switch. At least one actuating member is movably provided within the interior space and is formed integrally with an operating stub positioned in the slit for selectively braking and making an electrical connection between a pair of contacts fixed on the base in aligned and spaced relation. The slit has a center neck whose width is slightly smaller than the diameter of the operating stub for detenting movement of the actuating member. The actuating member side walls is positioned on housing base rails to maintain constant pressure between the actuating member conductive bridging strip and fixed pair of contacts.

  • Patent number: 4383145
    Abstract: A switch having a plate like matrix with laterally spaced longitudinally extending bores extending from one end of the plate to the other and wires resting in the bores with bare parts of the wires extending through the bores and insulating parts of the wires received in notches at one end of the plate. The plate has openings in one side communicating with the bare wires so that a slider sliding on the plate engages the wires through the openings forming contact with the wires and connecting the wires together at the proper positions of the slider thereby providing a switch for electrically connecting the wires together at selected positions of the slider on the plate.

  • Patent number: 4352966
    Abstract: A slider consisting of a one or two piece body with resilient contact switch members projecting in opposite directions at spaced intervals along the length of the slider to be in contact with a collector plate on one side and a respective one of spaced contactors at the opposite side. A plurality of ribs or protuberances which are located in the line of movement of the switch members, causes resilient deformation of the switch members to hold the switch in position once it snap fits into one or another of its respective switch positions. The protuberances may be either projections formed integrally in a switch body or on the collector plates.

  • Patent number: 4332987
    Abstract: A DIP switch is disclosed comprising improved sliding actuator means receivable within a rectangular housing channel. The slide actuator comprises a dielectric body having a plurality of parallel arms projecting forward therefrom, with each of the arms having a free, reversely formed end segment projecting backward in superior relationship to the actuator body. The slide actuator further comprises a plurality of parallel conductive arms, electrically and mechanically connected at one end, and projecting rearwardly from the actuator body. Each of the conductive arms is formed to provide a reversely-bent depending end segment projecting downwardly for engaging and interconnecting appropriate circuitry in the housing channel. A cover is further provided for enclosing the top of the housing channel, and provides a series of corrugations along a bottom surface thereof which are engaged by the superior actuator arm segments to register the actuator slide body along the housing channel.
