Abstract
Abstract An actuating member for a switch mounted on a circuit board has a projection that moves therewith and which slidably engages the board, so that the knob is reliably guided in a defined path as it actuates the switch. Preferably, the actuating member comprises knob on which the projection is formed, and the board has a slot for receiving the projection.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
67 words
In combination with a switch mounted on a board, said switch having a slidable actuating member spaced from said board and movable in a given direction between operative positions; guiding means for said actuating member comprising a part extending from said actuating member toward said board and movable with said actuating member in slidable engagement with said board as said actuating member moves in said given direction.
Claim 2
Dependent Claim
67 words
In combination with a switch mounted on a board, said switch having a slidable actuating member spaced from said board and movable in a given direction between operative positions; guiding means for said actuating member comprising a part extending from said actuating member toward said board and movable with said actuating member in slidable engagement with said board as said actuating member moves in said given direction.
Claim 3
Dependent Claim
42 words
The combination of claim 1, in which said board is provided with a slot extending in said given direction and said part is at least partially received in and slidable along said slot as said acTuating member moves in said given direction.
Claim 4
Dependent Claim
40 words
The combination of claim 2, in which said part is substantially T-shaped, comprising a stem and an upper head, said stem being slidably received in said slot and said head engaging and sliding over the upper surface of said board.
Claim 5
Dependent Claim
76 words
The combination of claim 3, in which said part further comprises a lower head spaced from said upper head by a distance substantially the same as the thickness of the slotted portion of said board, thereby to engage and slide over the lower surface of said board as said upper head engages and slides over the upper surface of said board, thereby to restrain movements of said actuating means in a direction perpendicular to said board.
Claim 6
Dependent Claim
37 words
The combination of claim 3, in which the width of said slot is slightly greater than the width of said stem, whereby movement of said actuating means is restrained in a direction lateral of said given direction.
Claim 7
Dependent Claim
21 words
The combination of claim 2, in which said slot permits only translation motions of said actuating member in said given direction.
Claim 8
Dependent Claim
14 words
The combination of claim 6, in which said translational motion is a linear motion.
Claim 9
Dependent Claim
21 words
The combination of claim 1, wherein said actuating member comprises a knob and said part is integrally formed with said knob.
