Abstract

833,336. Snap-action switches; press-button retractive switches. BEER, D. C. Nov. 19, 1956 [Nov. 18, 1955], No. 33069/55. Class 38 (5). A switch comprises a rigid rocker 5 pivoted on a fixed support 3 at 6, and a movable contact carrier 4 also fixed to the support 3, a bowed spring 14 being arranged between the rocker and carrier so as to give a snap-action when the rocker is moved by a plunger 16. The movement of the rocker is limited by a stop 25, or a surface on the housing (Fig. 1 (Comp.), not shown), so that the angle BCD is always obtuse and is always on the same side of the line BD, thereby ensuring that there is a thrust in the rocker which will restore the parts to the position shown when the plunger is released. The latter may be replaced by dolly-operated cam. As shown, the member 4 is a spring blade but may be rigid, and instead of being forked, as shown, could be T-shaped, the head of the T carrying the cbntacts. In this case, the rocker could have a portion on each side of the stem of the T, each with a separate bowed spring or a single spring could have a cut-out through which the stem passes.
