Abstract

737,250. Rotary switches. BAYS, F. Nov. 18, 1953, No. 31963/53. Class 38 (5). A switch comprises a number of units each of which is secured to its neighbour by connecting means common only to the two units. Each unit comprises a hollowed-out base 1 carrying spring contact blades 4 which are operable by rollers 3 arranged in selected recesses on the edge of a cam disc 2. Each disc 2 has a squaresection recess 14 engageable by a corresponding projection 13 on the adjacent disc, or by a square sleeve operable by a handle 11. The bases 1 are connected by bolts 12, which screw into each other. A base 6 houses a locating mechanism comprising a toothed wheel 8 and rollers (Fig. 4, not shown), and the rotation of the cams is limited by one or more pins 16 on wheel 8 and working in an arcuate groove 17 in base 6. Sectional housing members 20 are clamped between covers 21, 22.
