Abstract

776,288. Retractive switches. DUNLOP RUBBER CO., Ltd. Aug. 11, 1955 [Aug. 20, 1954], No. 24239/54. Class 38(5) A retractive push button switch comprises a plunger 13 upwardly urged by a spring 12, and a U-shaped spring 6 the ends of which are connected to the plunger by solid toggle links 16 so that on depression of the plunger the spring moves upwards with snap action bring- ing a bridging contact 7 into engagement with fixed contacts 18a. The bridging contact 7 is mounted for pivotal movement on a reentrant in the base of U-spring. The fixed rontacts are H shaped (Fig. 3), the cross bars 18a forming the contact portions and the sides being located in vertical holes in a member. 9 and the base 2. The member 9 forms a seating for the spring 12 and has slots through which the legs of the U-spring pass. A flexible cover 4 renders the switch dirt and moisture proof. In a modification (Fig. 2, not shown), the contacts are opened on depression of the plunger instead of being closed.
