Abstract

1331926 Retractive switches; switch actuators CUTLER HAMMER INTERNATIONAL FINANCE Inc 25 Feb 1972 [25 Feb 1971] 8811/72 Heading H1N In order to render additional actuating force necessary on the operating lever 18 of a miniature snap-action switch 4 and to damp vibrations of the lever 18, an auxiliary support member 2 formed of a resilient material such as rubber is inserted in a recess 6f in one side 6c of the insulating housing 6 between the actuator 16 and the point at which the lever 18 is pivoted, said member 2 extending from the housing 6 to support the lever 18 in a position spaced from the actuator 16, whereby the member 2 is compressed (Fig. 3, not shown) by the lever 18 before it engages the actuator 16. The lever 18 preferably has lateral extensions 18a engaged in depressions 6h formed in the sides of a further recess 6g in the side 6c of housing 6. The member 2 is shaped to require compression to fit in recess 6f and to be retained therein by its foot portion 2d. The additional force needed to actuate the switch may be selected by using a material of suitable resilience for the member 2.
