Abstract
1,011,434. Actuating devices for switches. GRUNDIG, M., [trading as GRUNDIG ELEKTRO - MECHANISCHE VERSUCHSANSTALT]. Dec. 23, 1963 [Jan. 29, 1963], No. 50600/63. Heading H2B. To reduce the wear on the pivots of an operating lever 4 bearing on the plunger 9 of a micro-switch 1 the pivot axis A is arranged to lie in a plane perpendicular to the axis of the plunger and midway of the total travel of that part of the plunger engaged by the operating lever, thereby obtaining minimum relative movement between plunger and lever. Four embodiments are described, in each of which the lever 4 passes through a slot in a bracket 2. attached to the switch 1 and has shoulders 6 locating it longitudinally in the one direction. In the embodiment of Fig. 1 a pressed-out tongue 5 limits movement in the other direction and a back stop 3 extends from bracket 2. Alternatively, a small compression spring may be mounted in a cut-out in place of tongue 5 and acts between the end of lever 4 and bracket 2 (Fig. 3, not shown); or a tension spring may extend between the back stop and the lever (Fig. 4, not shown). In the embodiment of Fig. 2 (not shown), the back stop 3 is omitted and two tongues are pressed out of the lever, one adjacent each side of bracket 2.
