Abstract
Abstract A slide switch of low profile particularly adapted for use with printed circuits. The terminals of the switch are stationary conductor pattern elements of the printed circuit and the movable contact parts are carried by a slider of insulating material. The slider is mounted in a circuit board slot which serves as a track for axial slider action. A caliper type mechanism (resilient detent arm) engages detent slots in the circuit board or provides the coupling means for ganging multiple switch stages to each other.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
209 words
A slide switch in which the stationary contacts are parts of the printed conductors of a printed circuit board and the movable contact parts are carried by a slide member of insulating material comprising the combination of: means defining a mounting slot through the thickness of said circuit board, said slot being elongated in the direction of actuation of said slide switch; slide mounting means for holding said slide in place with substantially only translational freedom in the direction of said actuation and with said movable contact parts in position to contact said stationary contacts, at least some parts associated with said slide protruding from the side of the board opposite said stationary contacts; a plurality of detent slots substantially along the actuation centerline of said mounting slot and spaced relationship at one end of said mounting slot; and detent means including at least one resilient detent arm having a nose engageable in one of said detent slots and being attached to said slide, said detent arm extending toward said detent slots and being adapted to exert lateral contact pressure on said board thereby to facilitate engagement of said nose into one of said detent slots in response to actuation of said switch to effect a corresponding switch position.
Claim 2
Dependent Claim
209 words
A slide switch in which the stationary contacts are parts of the printed conductors of a printed circuit board and the movable contact parts are carried by a slide member of insulating material comprising the combination of: means defining a mounting slot through the thickness of said circuit board, said slot being elongated in the direction of actuation of said slide switch; slide mounting means for holding said slide in place with substantially only translational freedom in the direction of said actuation and with said movable contact parts in position to contact said stationary contacts, at least some parts associated with said slide protruding from the side of the board opposite said stationary contacts; a plurality of detent slots substantially along the actuation centerline of said mounting slot and spaced relationship at one end of said mounting slot; and detent means including at least one resilient detent arm having a nose engageable in one of said detent slots and being attached to said slide, said detent arm extending toward said detent slots and being adapted to exert lateral contact pressure on said board thereby to facilitate engagement of said nose into one of said detent slots in response to actuation of said switch to effect a corresponding switch position.
Claim 3
Dependent Claim
69 words
Apparatus according to claim 1 in which said detent means is defined as a substantially identical caliperlike pair of said resilient arms extending from said slide toward said detent slots on opposite surfaces of said circuit board, whereby the corresponding noses of said resilient arms engage the same one of said detent slots from opposite sides of said circuit board to position said switch to a corresponding switch position.
Claim 4
Dependent Claim
67 words
The invention set forth in claim 2 in which said slide includes a head member having an undercut extending oppositely from the direction of extension of said resilient arms, whereby the resilient arms of a second one of said slides may be ganged thereto by sliding the resilient arms of said second slide over said head member until the noses of said resilient arms engage said undercut.
Claim 5
Dependent Claim
65 words
Apparatus according to claim 3 in which the lateral dimension of said head member and the depth of said undercut are such that said resilient arms mated thereto are spread laterally against their resiliency more than said resilient arms are spread when functioning as a detent mechanism, whereby the separation force is greater than the force required to actuate said switch from a detented position.
Claim 6
Dependent Claim
127 words
A slide sWitch in which the stationary contacts are parts of the printed conductors of a printed circuit board and the movable contact parts are carried by a slide member of insulating material, comprising the combination of: means defining a mounting slot through the thickness of said circuit board, said slot being elongated in the direction of actuation of said slide switch; and resilient means extending from said slide member through said slot, said resilient means being located and shaped to resiliently grip the edges of said mounting slot thereby to maintain contact pressure of said movable contact parts against the surface of said circuit board and said stationary contacts, and also to restrict said slide member from substantial movement except in the said direction of actuation.
Claim 7
Dependent Claim
127 words
A slide sWitch in which the stationary contacts are parts of the printed conductors of a printed circuit board and the movable contact parts are carried by a slide member of insulating material, comprising the combination of: means defining a mounting slot through the thickness of said circuit board, said slot being elongated in the direction of actuation of said slide switch; and resilient means extending from said slide member through said slot, said resilient means being located and shaped to resiliently grip the edges of said mounting slot thereby to maintain contact pressure of said movable contact parts against the surface of said circuit board and said stationary contacts, and also to restrict said slide member from substantial movement except in the said direction of actuation.
Claim 8
Dependent Claim
69 words
Apparatus according to claim 5 in which said resilient means extending through said slot comprise a plurality of resilient tongues extending substantially normal to said circuit board through said mounting slot, and means are included at the extreme end of each of said tongues for engaging the edges of said mounting slot to provide said contact pressure of said movable contact parts against the surface of said circuit board.
Claim 9
Dependent Claim
48 words
Apparatus according to claim 6 in which said tongues are four in number, two on each side of said slide in spaced relationship, and said means for engaging the edges of said mounting slot consists of a barblike nose at said extreme end of each of said tongues.
