Abstract
Abstract An on-off slide switch is arranged on a circuit board, preferably that of a battery-operated electronic clock, for actuating a stepping motor thereof. The slide switch can be moved to different positions and interacts with several electric paths of the circuit board. The switch is arranged movably along one edge of the circuit board and bears against such edge via guide elements. The switch carries at least one contact element for shunting a plurality of tracks of the board and a grip for its manual operation. The slide switch, together with all elements carried by it is designed in the form of a punched-out, flexible metal part and is easily installed on or removed from the circuit board without the need for separate fasteners.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
202 words
A slide switch in combination with a circuit board of the type which is generally planar having opposed surfaces and a peripheral edge extending between said surfaces, one of said surfaces including electrical conductor tracks, said switch comprising: a guide bar disposed in facing relationship with said edge and carrying a hand-manipulable grip projecting away from said edge to enable said guide bar to be slid relative to said edge between a plurality of positions, and guide means extending from opposite sides of said guide bar in stradling relationship with said circuit board, and in resilient gripping engagement therewith to frictionally mount said switch on said circuit board, said guide means including: a contact element extending from one side of said guide bar and across said one surface of said circuit board, said contact element including contact fingers which resiliently engage and electrically interconnect respective ones of said conductive tracks when said guide bar is in one of said positions, and a pair of guide elements extending from the opposite side of said guide bar and across the other surface of said circuit board in resilient engagement with said other surface with a force directed opposite to that of said contact fingers.
Claim 2
Dependent Claim
202 words
A slide switch in combination with a circuit board of the type which is generally planar having opposed surfaces and a peripheral edge extending between said surfaces, one of said surfaces including electrical conductor tracks, said switch comprising: a guide bar disposed in facing relationship with said edge and carrying a hand-manipulable grip projecting away from said edge to enable said guide bar to be slid relative to said edge between a plurality of positions, and guide means extending from opposite sides of said guide bar in stradling relationship with said circuit board, and in resilient gripping engagement therewith to frictionally mount said switch on said circuit board, said guide means including: a contact element extending from one side of said guide bar and across said one surface of said circuit board, said contact element including contact fingers which resiliently engage and electrically interconnect respective ones of said conductive tracks when said guide bar is in one of said positions, and a pair of guide elements extending from the opposite side of said guide bar and across the other surface of said circuit board in resilient engagement with said other surface with a force directed opposite to that of said contact fingers.
Claim 3
Dependent Claim
21 words
Apparatus according to claim 1 wherein said guide bar, guide elements, contact element, and grip comprise a one-piece, punched-out metal component.
Claim 4
Dependent Claim
30 words
Apparatus according to claim 1, wherein said guide bar, and guide elements are injection molded of synthetic material, said contact element formed of metal and embedded within said synthetic material.
Claim 5
Dependent Claim
31 words
A slide switch according to claim 1, wherein both ends of said guide bar extend parallel to said edge beyond said guide means to form guide portions which contact said edge.
Claim 6
Dependent Claim
52 words
A slide switch according to claim 1, wherein one of said guide elements includes a nipple projecting toward said circuit board, said circuit board including at least one recess for releasably receiving said nipple in a manner tending to retain said nipple therein at one of said positions of said guide bar.
Claim 7
Dependent Claim
92 words
A slide switch according to claim 1, further in combination with a clock of the type having a housing with front, rear, and side walls, a gear mechanism inserted into said housing perpendicularly to said front wall, said rear wall being insertable onto said housing and having a slot, said circuit being inserted edge-wise into said housing in the same direction as said gear mechanism so as to lie substantially parallel to said side walls, said switch being oriented so as to project through said slot upon installation of said rear wall.
