  • Patent number: 5828024
    Abstract: A switch includes a resilient contact plate that slides by operating an operating lever such as a pushing lever protruding from a housing. Terminal plates over which the resilient contact plate slides are attached so that the ends protrude into recesses formed in the bottom of the housing. Contact and, contact terminals fit into the recesses of the housing have resilient clamps that resiliently clamp the ends of the terminal plates extending into the recesses and blade terminals of bus bars rising from an insulated base.

  • Patent number: 5824977
    Abstract: A slide switch includes a moving contact contained within a slider that moves between a plurality of desired stationary contacts. A clicking thruster provided with resiliency by a resilient member such as a spring produces a clicking sensation during switching by engaging with clicking thruster recesses. A through hole is provided in the slider, and the moving contact is positioned within the through hole in opposition to the stationary contacts. The clicking thruster is positioned in opposition to the clicking thruster recesses, and the resilient member is fit in between the moving contact and the clicking thruster.

  • Patent number: 5803242
    Abstract: Switch connecting structures include a housing having an insertion hole, and an operation lever slidably mounted in the housing. The operation lever includes a push member protruding from said housing. A resilient contact plate is carried by the operation lever so as to be slidable therewith. A connection terminal is provided having a resilient clamp portion and a contact plate portion. The contact plate portion is inserted into the insertion hole of the housing and extending therewithin over a range of slidable movement of the operation lever so as to be in contact with the resilient contact plate. In such a manner, the clamp portion is connectable to a bus bar for electrical connection of the switch to a circuit.
