Abstract

1,214,695. Cam operated switches. H. L. NAIMER. 18 June, 1968 [23 June, 1967], No. 29030/68. Heading H1N. The operating programme of a switch assembly comprising a plurality of bridging contacts 6 actuated by a rotary cam 4 is adjustable by axial movement of the shaft 3 carrying the cam 4 to present a different cam profile of the cam to the cam followers 5 of the bridging contacts. A plurality of switch assemblies may be stacked together for operation by respective rotary cams 4 secured to a common shaft 3. The switch device shown has two switch assemblies and the shaft is biased upwardly by springs 12 beneath each cam 4 or by pairs of springs (not shown) acting against'a projecting plate 22 secured to its cam. The operating shaft carries a keyplate 10 which cooperates with a complementary fixed keying plate 14 to ensure that axial movement of the shaft to change the programme can only be effected in certain angular positions. The axial movement of the cams 4 may cause operation of the switch assemblies by means of surfaces 46. The cams shown have two axial spaced profiles but more than two may be provided. In the latter case more than two sets of key plates and keying plates are provided and the arrangement can be such that the cam or cams carries out a series of axial movements from one programme level to another during a single rotation.
