Abstract: A control device comprising an electrical switch having an actuator disposed for reciprocal movement in a housing and provided with a substantially planar surface whereon a pawl is mounted for rotation in a plane adjacent the planar surface. The pawl includes a plurality of cam surface portions disposed for engagement with projections within the housing to convert reciprocal movement of the actuator into controlled rotary movement of the pawl in a uniform direction and thereby determine the sequence of operating conditions produced by the actuator. At least one pair of resilient arms extend from respective opposing portions of the pawl and into resilient pressure engagement with the substantially planar surface for exerting respective balanced tensile forces on the opposing portions of the pawl and enabling the pawl to resist free rotary movements and permit controlled rotary movements thereof.

Abstract: A male plug connector having terminals coupled to the signal leads of an electrical circuit for switching the signal leads dependent upon interfitting or separating the male connector with a mating female connector. First, second and third electrodes longitudinally extend through a post-like insulating base thereby defining three respective male pins protruding from the mating face of the base and three respective terminals protruding from the opposing face of the base. A fourth electrode protrudes only from the opposing face to define a fourth terminal. A spring loaded plunger is slidably positioned in the base and protrudes from the mating face of the base. The plunger is mechanically linked to an axially sliding switch which has three interconnected contact arms aligned with the second, third and fourth electrodes. During interfittment of the connectors, the plunger is inwardly deflected by the face of the female connector thereby electrically interconnecting the third and fourth terminals.

Abstract: An electrical jack having a housing of insulating material with integral walls thereof forming a cavity. A front wall of the housing has an axially extending hollow collar member with a passageway for guiding a stem of a jack plug into the cavity. A plurality of spring contactor electrodes are disposed within the housing cavity and are adapted to engage predetermined portions of the jack plug stem when such stem is inserted into the cavity to establish electrically conductive paths between the contactor electrodes and the portions of the jack plug. An additional electrical contactor, having an aperture formed in a mounting portion thereof, is disposed around the collar member, such mounting portion being disposed outside the housing cavity. The additional electrical contactor has a finger electrode protruding across the front wall into the cavity to electrically contact a portion of the inserted jack stem.

Abstract: An actuator button assembly for a push-button switch having a reciprocally movable actuator shaft, the button assembly including a shell mounted on the shaft and having an end surface lens, a rotor carrying a peripheral array of position indicating panels and mounted within the shell for rotation about an axis substantially parallel with said lens, the rotor having an end surface provided with a radially extending slot, and a fixed arm extended within said slot for converting reciprocal movement of the actuator shaft into rotary movement of the rotor to align a respective one of said panels with said lens for indicating the operative condition of the switch.

Abstract: An improved electrical slide switch having a housing portion, a slidable actuator within the housing, and a resiliently engageable and removable cap which may itself be the actuator, the actuator having a pair of precisely spaced integral leaflike elements which form a trackway of predetermined length which slide over an integral centrally disposed fixed pin carried by the base, with the pin being adapted to repose at opposite ends of the trackway when terminals within the housing are properly engaged with selected slider elements carried by the actuator.

Abstract: An improved electrical slide switch is provided having electrically conducting terminals embedded in a molded supporting structure thereby eliminating the conventional terminal board in which the terminals have to be mounted in openings provided for that purpose, and further characterized by slidable contacting elements which reduce to a minimum frictional contact during position changes thereby reducing wear and increasing the durability.
