Abstract

532,336. Rotary switches. ARNOLD, C. L., and M. K. ELECTRIC, Ltd. July 26, 1939, No. 21713. [Class 38 (v)] A switch suitable for electric fires &c. has a spindle 11 carrying a cam 12, for operating a movable contact 6, and an operating member which can be rotated always in one direction and which forms a closure for the aperture in the cover plate through which it passes. The operating member may be a notched disc or, as shown, it may comprise four arms 13 arranged at right angles to each other rand adapted to move in a recess in the centre of the switch base. The contact 6 moves in a recess at one side of the base and at the other side a spring-pressed ball or plunger may be arranged to engage a four-sided cam to determine the switch positions.
