Title: Selector switch
IPC: H01H19/11
Filed: 1960-12-05
Abstract: 973,860. Mechanical switches, without quick action; distributers. R. E. HARTSOCK. Dec. 5, 1961 [Dec. 6, 1960], No. 43554/61. Heading H2B. A selector switch comprises an insulating board 1 having guide rails 2 between which a scanning plate 8 can be moved longitudinally by rotation of a cardioid cam 13 acting on two pins 12 secured to the plate 8. The plate 8 is narrower than the distance between rails 2 and is given a lateral movement when a pin 12 is engaged by the cusp of the cam 13 (Figs. 5 and 6, not shown); thus a complete revolution of cam 13 causes plate 8 to describe a substantially rectangular path. Board 1 carries contacts 4, 6, and 4<SP>1</SP>, 6<SP>1</SP> with respective common conductor strips 5 and 5<SP>1</SP>, all of which, together with connections to terminals 7, may be applied by printed circuit technique. Plate 8 is provided with holes 9, to selected ones of which spring contacts 10 are riveted for cooperation with the fixed contacts on board 1. The spring contacts 10 also serve to urge plate 8 against flanges 3 extending from the rails 2. As cam 13 is rotated by a knob 16 plate 8 moves longitudinally causing contacts 10 to successively bridge contacts 4, 5 and 4<SP>1</SP>, 5<SP>1</SP>, until the cusp of the cam 13 engages a pin 12 when plate 8 is shifted laterally and further rotation of knob 16 moves contacts 10 over fixed contacts 5, 6 and 5<SP>1</SP>, 6<SP>1</SP>. The shaft 14 coupling knob 16 to cam 13 carries a notched disc 21 which cooperates with a U-shaped spring detent 22 to locate the positions of plate 8 wherein contacts 10 lie on the respective contacts 4, 4<SP>1</SP>, or 6, 6<SP>1</SP>. The size of cam 13 is chosen to determine the number of contacts to be successively engaged. The common conductor strips 5, 5<SP>1</SP> may be divided into separate sections (Fig. 7, not shown). In a modification (Fig. 10, not shown) the shaft 14 may be journalled in the centre of board 1 and extend through an opening in plate 8 to the cam 13. The path of plate 8 may be limited to only part of a rectangle (Figs. 25 and 26, not shown) by bending up one or more arms of a star wheel 25 which rotates with cam 13 to abut a lug on the spring detent 22 (Fig. 9, not shown). In a further modification, the lateral movement of plate 8 is arcuate (Fig. 27, not shown) and the plate is guided by two depending pins thereon engaging in slots in a bar attached to board 1 (Figs. 11 and 12, not shown). The cam 13 may be motor-driven for continuous operation, in which case the detent 22 and disc 21 can be omitted. The fixed contacts and moving spring contacts may be more complicated for special cases (Figs. 17 and 18, not shown). The board 1 and plate 8 may be made by cutting suitable lengths from continuous strip (Figs. 13 and 14, not shown).
