Abstract:
The present invention relates to a multiple push-switch apparatus comprising an exclusion mechanism which includes a plurality of slidably supported operation bodies and a flexible body, any one of said plurality of operation bodies being able to move by means of said flexible body, and a plurality of electric switches which are driven by said plurality of operation bodies, respectively. In addition, there is provided a multiple push-switch apparatus especially suitable as a station selecting apparatus for a television receiver. The apparatus can be operated by the use of a soft touch, permits the employment of various operation body arrangements, and prevents simultaneous operation of a plurality of electric switches by mistake.
Abstract:
An interlocking pushbutton key switch is disclosed in which the interlocking slide bar has a lipped, toothed extension which engages in a rotatably mounted, coupling plate. Other rows of pushbuttons are constructed to operate similarly. Thus the operation of one button in any row interlocks with all other pushbuttons on the pushbutton key switch assembly.
Abstract:
A push button switch unit comprises a mounting chassis with push button switches, the chassis having a housing plate adjacent to the push button switches on the chassis plate. Flat locking slides are mounted between the chassis plate and the housing plate so as to be able to move side-ways for coordinating the operation of plungers of the switches. The unit includes for each switch a locking pin extending into a hole in the plunger of the respective switch, the hole being perpendicular to the axis of the plunger. An opening is provided in the chassis plate and a slot, corresponding in length to the stroke of the respective plunger, is provided in the switch unit housing plate. The locking pin is arranged to be inserted through the opening in the chassis plate and the slot in the housing plate. The unit further comprises a locking slide adapted to cooperate with the head of the locking pin.
Abstract:
A selecting apparatus includes a plurality of selector input switches, each of which is representative of a character utilized to identify selections in a vending machine and each of which is individually actuatable by an associated actuator. Additional input switches are provided for supplemental switching functions. The actuators are adapted for displacement beyond the contact mating position in order to close a common master switch, which controls energization of the circuits containing the selector input switches, after the input switch has been closed. Each input switch actuator has a spring-biased contact holder and is assembled by utilizing a restraining collar with a latching member to position the spring.
Abstract:
An improved push button switch includes a single body plate with assembled push rods or actuators fastened to the single body plate and cooperable with moving disc members, a ratchet and spring, or biasing means. The disc members are held in position by a bracket, the bracket also being fastened to the single body plate. Contact blocks are fastened to the outside of the bracket and cooperate with assembled contact cam block members of the push rods or actuators. Biasing leaf springs of the contact blocks cooperate with the actuators to facilitate switching action. A push button fastens to the end of the actuators to secure alignment of the actuators through a front plate of the switch and provide a manual interface to the operator.
Abstract:
A switch adapted for as an A-B coaxial cable switch for CATV systems. The switch includes a pair of depressible pushbuttons, one for each cable. The buttons always move oppositely to each other. The crossbar extends diagonally within the switch and pivots at its center on a stationary slot in the switch housing. The ends of the crossbar pivot on slots in longitudinally reciprocable bars connected to the pushbuttons. A pair of coil springs are connected between the ends of the crossbar and the housing. Movable contact members carried by the bars make or break brushing contact with stationary spring contacts each time the pushbuttons are switched. When either button is depressed to move the crossbar past center or lateral position, the coil springs urge the crossbar toward the reverse position.
Abstract:
A peg or annunciator board device for offices and plants to indicate disposition of personnel. Aligned rows of pegs of lighttransmitting material which glow, when pressed inwards, from light from a source within the device. Automatic latching of a single peg or group of pegs when pressed inwards and individual or multiple peg release.
