Split Housing Patents (Class 200/303)
  • Patent number: 3975604
    Abstract: The rear cover of a switch housing is removble and supports a plurality of individual switch units. Each switch unit has an axially positioned switch actuating plunger. The housing has a push-button mechanism positioned to contact the switch plungers. On the exterior of the switch unit are spring contacts which engage spring contacts on the housing. The housing has wiring connectors electrically connected to the housing spring contacts. By removal of the rear cover the switch units are withdrawn from the housing without the necessity for disconnecting the wires. The switch units and housing components can be stacked so as to increase the number of switches actuated by the push-button mechanism.

  • Patent number: 3971904
    Abstract: An ignition switch for the selective ignition of a gas tap assembly that is controlled by a rotatable gas tap spindle is disclosed. The switch has an aperture which receives the gas tap spindle. Opening and closing of the gas tap is achieved by rotation of the spindle. Rotation of the spindle causes rotation of a cam in the aperture of the switch to control the making and breaking of a pair of electrical contacts. The contacts have relatively thick terminal portions that are secured in the housing with their outer ends extending into openings which receive insulated sockets. The contact members are L-shaped and have relatively thin contact portions which are positioned so that one portion overlies the other and both of them overlie the rotatable cam.

  • Patent number: 3944760
    Abstract: A switch assembly provides a plurality of slide switches. Each switch employs a flexible guide rod cantilevered within a common housing providing a first contact. A second contact is biased into electrical contact with each guide rod and an insulative cam carried by a switch actuator is supported by each guide rod for rectilinear movement therealong in an interference path with the second contact to separate the second contact from the guide rod. The flexible guide rod is movable with respect to the second contact and provides the means to align the switch actuator and the cam in an interference path with the second contact. Each switch actuator provides a pair of side walls enclosing a respective guide rod and second contact suspended therebetween.
