A coded switch unit is provided with code setting means adjustable between two positions and a plurality of pushbutton actuated operating means also adjustable between two positions and cooperating with contact means in such a manner that depending upon the adjusted position of the code setting means and the operating means, closing of a circuit connected to the switch will require actuation of operating means set in one position, whereas actuation of any operating means set in the other position will prevent closing of the circuit.
A push-button switch assembly is provided and includes one or more banks of push-button switches. Each switch includes a switch body shiftable between first and second limit positions and a third intermediate position. Each switch also includes a switch actuator also shiftable between first and second limit positions and a third intermediate position. A pair of push-buttons is provided for each switch and each pair of push-buttons is operable to shift the corresponding switch actuator between the first and second limit positions thereof. The switch bodies each include a pair of spaced terminals and the switch actuators each include terminal bridging means for bridging the corresponding terminals when the actuator is in a position thereof corresponding to the position of the associated switch body. In the instant invention, the switch assembly is disclosed as operatively associated with a door latch operating mechanism of the solenoid type and selected switches of the bank of switches may be operatively associated with the door latch operating mechanism and must have a proper button actuator thereof depressed in order to enable the door latch actuator to operate. Any of the switches not operatively associated with the door latch operating mechanism may be connected to suitable alarm systems, porch lights, and warning systems in an adjacent neighbors house, or remote police station. Also, the door lock push-button control is adapted for actuation not only by house current, but also includes a provision whereby a battery may be positioned in place from outside the associated door and electrically connected to the push-button control assembly in the event of failure of the domestic house current, the insertion of a battery into its proper position automatically opening the circuit by which the switch is normally supplied current from domestic supply and connecting the battery to the control system in lieu of the domestic current.
The electrical circuits of a vehicle are controlled by a circuit breaker, a combination register and an ignition switch in such manner as to prevent unauthorized individuals from operating a vehicle. The breaker has a control arm which can be placed manually in any one of three positions.
