    Abstract: A multi-pole switch includes a wobble stick type actuator provided with a contactor engaging the free end portions of a plurality of displaceable resilient inner pin contacts having their base portions fixedly mounted in a support member. A plurality of stationary pin contacts are disposed radially outside and adjacent said displaceable pin contacts. A guide member adjacent the contactor includes a plurality of radially extending slots therethrough each housing a portion of one of the displaceable pin contacts and one of the stationary pin contacts in a normally spaced apart manner. A biasing element normally maintains the contactor in a central, neutral position whereby, upon deflection of the actuator the contactor is radially displaced and correspondingly displaces a selected inner pin contact into engagement with its radially adjacent stationary pin contact in the same guide member slot to close a circuit between the engaging contacts.

    Abstract: A remotely adjustable mirror assembly in which a reflective member is supported on a tilting mechanism which includes a pair of selectively movable ramped cams. The cams are coupled to gripper devices to grip or release a member which is reciprocated by a pair of alternately energized solenoids. The gripper devices are also solenoid operated and include either a recessed head or a double-gag plate head to grip or release the reciprocating member. A multiposition, joy-stick operated switch provides eight operating modes for selectively adjusting the position of the member in azimuth, or elevation, or both. A pulse generator producing two trains of oppositely phased pulses is connected through the multiposition switch to the solenoids for the reciprocating member. Two types of switch are described.

    Abstract: The normally provided manually operable switch lever on an electrically drive wheelchair incorporates pairs of switch arms so that additional circuitry can be provided for interconnection with the normally provided left and right wheel drive motors. This additional circuitry comprises electrical resistances arranged to be connected across the motor leads by the manually operable switch when in an unactuated position for the particular motor in question. The provision of these resistances across the motor leads when the motors are unenergized results in absorption of back voltage spikes to thereby avoid burning out the switch means, dynamic braking when the motors acts as generators as a result of the wheelchair coasting, easier steering control when only one of the motors is energized to effect a turn, and permits the use of permanent magnet type d.c. motors for the left and right wheel drive motors.

    Abstract: A hand-held controller device including a two-piece outer housing shaped to be held in one hand of the user, an internal cylinder pivoted at one end and adapted to telescopically receive an elogated plunger from the other end, the plunger having a contact pin attached to the received end and a hand grip knob affixed to its other end. A first plurality of switch contacts are carried by the cylinder so as to engage a stationary contact in response to the pivotal positioning of the cylinder, and a second plurality of contact elements are also carried by the cylinder and engaged by the contact pin in response to the longitudinal positioning and the rotational positioning of the plunger.

    Abstract: In a preferred form, this disclosure relates to a light switch assembly having a housing means carrying a stationary ground terminal and a plurality of stationary terminals positioned in a spaced relationship about the ground terminal, a pivotally supported bridging contact member, and a swivelly supported actuator means. The bridging contact member is pivotally supported upon the ground terminal for movement to different positions to bridge different ones of the stationary terminals and the ground terminal. The actuator means is swivelly supported by the housing means for pivoting the bridging contact member to different positions. Further, the actuator means includes a plunger member which is spring biased into engagement with a dome portion on the bridging contact member. The plunger member rolls in engagement with the dome portion when the actuator means is manipulated to maintain a substantially equal distribution of pressure upon the bridging contact member when it is moved to its different positions.
