Abstract

Abstract An selector switch is disclosed which features conductive strips mounted on interior surfaces of spaced insulating boards. The strips are oriented in crossing relationship and a contact spring is slidably mounted between the boards so as to selectively contact a pair of crossing strips to provide an interconnection. The top board includes slots which define contact spring travel and allow a spring mounting element to extend above the top board for manipulation. A thin plastic grid is mounted over the lower board which serves a dual function by preventing conductive material of the strips thereon from being smeared to create a short between strips and also by providing an indexing action for each contact spring. The spring mounting elements are connected to thin flexible plastic tapes which follow the mounting elements in movement and cover the guide slots to minimize entry of foreign particles. Numerals printed on the tape are displayed through a window in the top board to provide symbolic indication of spring contact position.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 241 words
A switch assembly comprising first and second insulating boards each having a plurality of separate conductive paths on a surface thereof, one of said boards having a series of slots disposed between the conductive paths on such board and the other of said boards having a thin sheet of plastic material containing an array of apertures arranged in rows corresponding with the conductive paths on such board and in columns corresponding to the spacing between the said slots on the other of said boards, means securing said boards into an assembly with the slots and the conductive paths of said one board running generally crosswise to the conductive paths of the other board, a plurality of slide elements mounted in said assembly with a portion thereof extended through a slot to facilitate movement of said element, a further portion of said element fitted between said boards and containing a contact spring means having contact surfaces biased toward the conductive surfaces of two boards whereby movement of a given element in a given slot causes said spring means to wipe continuously along the conductive path of the said one board containing the slots and to wipe intermittedly over the separate conductive paths on the other board with said thin plastic sheet serving to preclude continuous contact with the upper surface of said other board to avoid wiping of the conductive material thereacross to short out said conductive paths of said other board.
Claim 2
Dependent Claim 241 words
A switch assembly comprising first and second insulating boards each having a plurality of separate conductive paths on a surface thereof, one of said boards having a series of slots disposed between the conductive paths on such board and the other of said boards having a thin sheet of plastic material containing an array of apertures arranged in rows corresponding with the conductive paths on such board and in columns corresponding to the spacing between the said slots on the other of said boards, means securing said boards into an assembly with the slots and the conductive paths of said one board running generally crosswise to the conductive paths of the other board, a plurality of slide elements mounted in said assembly with a portion thereof extended through a slot to facilitate movement of said element, a further portion of said element fitted between said boards and containing a contact spring means having contact surfaces biased toward the conductive surfaces of two boards whereby movement of a given element in a given slot causes said spring means to wipe continuously along the conductive path of the said one board containing the slots and to wipe intermittedly over the separate conductive paths on the other board with said thin plastic sheet serving to preclude continuous contact with the upper surface of said other board to avoid wiping of the conductive material thereacross to short out said conductive paths of said other board.
Claim 3
Dependent Claim 49 words
The assembly of claim 1 wherein each of said slide elements includes an insulating detent positioned to engage the apertures of said thin sheet to facilitate indexing movement of said element in said assembly and positioning of said contact surface on a given conductive path exposed by said aperture.
Claim 4
Dependent Claim 68 words
The assembly of claim 2 wherein said detent means is of a width approximating the width of the apertures in said sheet and is located relative to said contact surface to position said contact surface toward the center of the conductive path of the lower board when said element is moved to effect a given interconnection between the conductive paths on said one board and said other board.
Claim 5
Dependent Claim 103 words
The assembly of claim 1 wherein there is included a thin flexible tape member attached at one end of each slide element and there is provided means at one end of saiD assembly for spring loading said tape member in a sense to reel said tape member as said slide element is moved toward said means, the said tape member including indicia representative of the position of said slide element and there being provided in the upper board of said assembly an aperture for displaying said indicia as said slide element is moved and as said tape member is drawn past said aperture.
Claim 6
Dependent Claim 83 words
The assembly of claim 1 wherein there is provided for each slide element a thin, stiffly flexible tape member joined to said slide element to be moved thereby, means at each end of said assembly for receiving and coiling said tape member as said slide element is moved in a given slot, the said tape member having a width and being positioned relative to a slide element associated with a given slot to cover said slot, notwithstanding movement of said slide element therealong.
Claim 7
Dependent Claim 57 words
The assembly of claim 5 wherein the upper board of said assembly includes at least an aperture associated with at least certain of said slots and said tape member includes indicia thereon whereby movement of said slide element effects a display of said indicia through said aperture as an indication of slide element position and associated interconnection.
