  • Patent number: 5550342
    Abstract: A method and apparatus for an electrical switch assembly generally comprising a snap-action electrical switch disposed in a module frame assembly and connected to electrical contact pins for mating with a contact pin connector. A switch module assembly is connected to the module frame assembly and includes a switch actuator assembly for actuating the snap-action electrical switch. The switch actuator includes a latch spring guide that may be configured for either "alternate" or "momentary" actuation of the snap-action electrical switch and emits audio and tactile switch status indicators perceptible to an operator. The module frame assembly and switch module assembly are releasably connectable to and form an integral unit with a cap base assembly having a cap module with a low power LED illuminatable display visible under extreme ambient lighting conditions for indicating switch status.

  • Patent number: 4363087
    Abstract: A mounting post for holding a light emitting diode in an electrical pushbutton switch is formed by a cylindrical base which has a pair of cut-out sections located intermediate the top and bottom surfaces of the base which are diametrically opposed on opposite sides of the base. The cut-out sections divide a pair of elongated, parallel passageways for the leads of a light emitting diode (LED) or other light device into upper and lower segments so that a portion of the leads of the inserted LED are exposed in the cut-out sections. The leads of the LED are then crimped in the cut-out sections so that the lead forced against a rear wall of these sections with the leads being restrained from moving by engagement of the leads with upper and lower walls of the cut-out sections.
