Abstract

Abstract 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.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 159 words
A push-button control assembly including a support having a plurality of switch bodies supported therefrom for independent shifting relative to said support between first and second limit positions as well as third positions intermediate said first and second positions, each of said switch bodies including thereon an associated switch actuator also supported from said support for shifting relative thereto between the same first, second and third positions, each of said switch actuators including a pair of corresponding push-buttons operatively associated therewith for alternately shifting said actuators between said first and second positions thereof in response to alternate actuation of the corresponding push-buttons, said switch bodies each including a pair of spaced terminals shiftable therewith and said switch actuators each including terminal bridging means operative to electrically bridge the corresponding body terminals in response to said actuator being disposed in the first or second position thereof when the corresponding switch body is disposed in its first or second position, respectively.
Claim 2
Dependent Claim 159 words
A push-button control assembly including a support having a plurality of switch bodies supported therefrom for independent shifting relative to said support between first and second limit positions as well as third positions intermediate said first and second positions, each of said switch bodies including thereon an associated switch actuator also supported from said support for shifting relative thereto between the same first, second and third positions, each of said switch actuators including a pair of corresponding push-buttons operatively associated therewith for alternately shifting said actuators between said first and second positions thereof in response to alternate actuation of the corresponding push-buttons, said switch bodies each including a pair of spaced terminals shiftable therewith and said switch actuators each including terminal bridging means operative to electrically bridge the corresponding body terminals in response to said actuator being disposed in the first or second position thereof when the corresponding switch body is disposed in its first or second position, respectively.
Claim 3
Dependent Claim 23 words
The assembly of claim 1 including selectively actuatable return means operative to shift all of said switch actuators to said third positions thereof.
Claim 4
Dependent Claim 25 words
The assembly of claim 1 wherein said support and switch bodies include releasably actuatable means operative to retain said switch bodies in selected shifted positions.
Claim 5
Dependent Claim 32 words
The assembly of claim 1 wherein said support includes first electric current input means electrically connected to a conductor adapted for selective connection, in series, with the terminals of selected switch bodies.
Claim 6
Dependent Claim 16 words

Claim 9
Dependent Claim 54 words
The combination of claim 7 wherein said control assembly includes selectively actuatable return means operative to shift all of said switch actuators to said third positions thereof, said return means including a first actuator operable from said one side of said door and a second actuator operable from said other side of said door.
Claim 10
Dependent Claim 16 words
The assembly of claim 1 including a housing, said support bein removably supported in said housing.
Claim 11
Dependent Claim 25 words
The assembly of claim 9 wherein said support and switch bodies include releasably actuatable means operative to retain said switch bodies in selected shifted positionS.
Claim 12
Dependent Claim 39 words
The assembly of claim 10 in combination with a door, said assembly being supported from said door with said push-buttons accessible from one side of said door and said switch bodies accessible from the other side of said door.
Claim 13
Dependent Claim 117 words
A push-button control assembly including a support having a plurality of switch bodies supported therefrom for independent shifting relative to said support between first and second limit positions, each of said switch bodies including therein an associated switch actuator also supported from said support for shifting relative thereto between the same first and second positions, manually operable means for selectively shifting said actuators independenendently of said switch bodies between their first and second positions, said switch bodies including pairs of spaced terminals, said switch actuators each including terminal bridging means operative to electrically bridge the corresponding body terminals in response to said actuator being disposed in a position corresponding to the position of the associated switch body.
Claim 14
Dependent Claim 117 words
A push-button control assembly including a support having a plurality of switch bodies supported therefrom for independent shifting relative to said support between first and second limit positions, each of said switch bodies including therein an associated switch actuator also supported from said support for shifting relative thereto between the same first and second positions, manually operable means for selectively shifting said actuators independenendently of said switch bodies between their first and second positions, said switch bodies including pairs of spaced terminals, said switch actuators each including terminal bridging means operative to electrically bridge the corresponding body terminals in response to said actuator being disposed in a position corresponding to the position of the associated switch body.
