Abstract
Abstract A control or front panel assembly which is suitable for inclusion in associated apparatus. The panel assembly includes a switching arrangement with individual switch actuators easily detachable and removable during final assembly prior to mounting an escutcheon plate to the front panel face. In this manner, a single piece part need only be inventoried, modifiable during final assembly, to effect the desired model variations for the associated apparatus.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
133 words
A universal control panel assembly with a switching arrangement adaptable at final assembly to accommodate only those selectable option features provided by an associated PC board, comprising in combination: a control panel housing with means for mounting the associated PC board; an elastomeric key strip assembly having multiple switch assemblies with associated breakaway switch actuators mounted between said housing and PC board with each of said switch actuators extending through an associated opening in said housing and accessible to a user, said switch actuators being selectively and individually detachable by being pulled through said panel openings so that the remaining switch assemblies conform to the options provided by said PC board; and an escutcheon plate mounted to the front of said housing to accommodate the remaining switch actuators and identify the options selectable.
Claim 2
Dependent Claim
133 words
A universal control panel assembly with a switching arrangement adaptable at final assembly to accommodate only those selectable option features provided by an associated PC board, comprising in combination: a control panel housing with means for mounting the associated PC board; an elastomeric key strip assembly having multiple switch assemblies with associated breakaway switch actuators mounted between said housing and PC board with each of said switch actuators extending through an associated opening in said housing and accessible to a user, said switch actuators being selectively and individually detachable by being pulled through said panel openings so that the remaining switch assemblies conform to the options provided by said PC board; and an escutcheon plate mounted to the front of said housing to accommodate the remaining switch actuators and identify the options selectable.
Claim 3
Dependent Claim
26 words
A universal control panel assembly in accordance with claim 1 wherein said breakaway switch actuators are detachably connected together by a base strip of flexible webbing.
Claim 4
Dependent Claim
43 words
A universal control panel assembly in accordance with claim 2 wherein said webbing includes a reduced thickness portion between successive actuators, which portions are aligned with a respective inverted V-rib on said housing to provide a shear assist when extracting a selected actuator.
Claim 5
Dependent Claim
47 words
A universal control panel assembly in accordance with claim 2 wherein guide pins are included on said housing to align and mate with corresponding openings on said key strip assembly to hold and maintain the remaining actuators in place while a selected one thereof is being extracted.
Claim 6
Dependent Claim
64 words
A universal control panel assembly in accordance with claim 1 wherein the mounted said printed circuit board and key strip assembly includes one or more hook members on the panel housing overlying an edge portion on one side of said PC board and one or more complementary hook members extending through and latching in corresponding opening along the other edge of said PC board.
Claim 7
Dependent Claim
52 words
A universal control panel assembly in accordance with claim 1 wherein switching elements in the form of conductive runners are provided on said printed circuit board which are to be bridged across by at least one conductive pad on one of said actuator when the same is actuated by being depressed inwardly.
Claim 8
Dependent Claim
29 words
A universal control panel assembly in accordance with claim 6 wherein said actuator includes first and second conductive pads for contacting said switching elements on said printed circuit board.
Claim 9
Dependent Claim
106 words
A front panel assembly modifiable at final assembly and intended for inclusion with associated electrical apparatus, comprising in combination: a printed circuit board; a control panel housing with means for mounting the associated PC board; and an elastomeric key strip assembly having multiple switch assemblies with associated breakaway switch actuators mounted between said housing and PC board with each of said switch actuators extending through an associated opening in said housing for accessibility by a user, said switch actuators being selectively and individually detachable by being pulled through said panel openings so that the remaining switch assemblies conform to the options provided by said PC board.
Claim 10
Dependent Claim
106 words
A front panel assembly modifiable at final assembly and intended for inclusion with associated electrical apparatus, comprising in combination: a printed circuit board; a control panel housing with means for mounting the associated PC board; and an elastomeric key strip assembly having multiple switch assemblies with associated breakaway switch actuators mounted between said housing and PC board with each of said switch actuators extending through an associated opening in said housing for accessibility by a user, said switch actuators being selectively and individually detachable by being pulled through said panel openings so that the remaining switch assemblies conform to the options provided by said PC board.
Claim 11
Dependent Claim
26 words
A modifiable front panel assembly in accordance with claim 8 wherein said breakaway switch actuators are detachably connected together by a base strip of flexible webbing.
Claim 12
Dependent Claim
43 words
A modifiable front panel assembly in accordance with claim 9 wherein said webbing includes a reduced thickness portion between successive actuators which portions are aligned with a respective inverted V-rib on said housing to provide a sheer assist when extracting a selected actuator.
Claim 13
Dependent Claim
47 words
A modifiable front panel assembly in accordance with claim 9 wherein guide pins are included on said housing to align and mate with corresponding openings on said key strip assembly to hold and maintain the remaining actuators in place while a selected one thereof is being extracted.
Claim 14
Dependent Claim
64 words
A modifiable front panel assembly in accordance with claim 8 wherein the mounted said printed circuit board and key strip assembly includes one or more hook members on the panel housing overlying an edge portion on one side of said PC board and one or more complementary hook members extending through and latching in corresponding opening along the other edge of said PC board.
Claim 15
Dependent Claim
52 words
A modifiable front panel assembly in accordance with claim 8 wherein switching elements in the form of conductive runners are provided on said printed circuit board which are to be bridged across by at least one conductive pad on one of said actuators when the same is actuated by being depressed inwardly.
