Abstract

1,051,897. Press-button retractive switches; switch cases. STANDARD TELEPHONES & CABLES Ltd. June 5. 1964 [June 11, 1963], No. 23417/64. Heading H2B. A push-button assembly comprising a base plate 20, having a co-ordinate array of intersecting vertical and horizontal guideways 23-28 therein, has sinusoidal shaped wire springs such as 41, 42 in each guideway, such that downward motion of a push-button such as 31 at any of the intersections 30 is converted into longitudinal motion along the guideways of the corresponding two wire springs and consequent operation of two microswitches such as 46, 47. The push-buttons are guided in the cover-plate 22 and in the intersections 30 on the base-plate 20, and a snap feel is provided when the push-button is depressed by the wire springs passing over projections on the guideway walls (Fig. 4, not shown). Larger push-button assemblies are made by ganging together a plurality of assemblies (Fig. 5, not shown).
