Abstract

798,638. Retractive switcher; actuation of switches; cases. MAXSON CORPORATION, W. L. July 16, 1956 [July 26, 1955], No. 21947/56. Class 38 (5). A dead-centre snapping-blade switch comprises similar housing-parts 10, 11, a snapping- blade 29 and support 25 therefor, contactcarriers 45, 46, and plunger 17, all formed so as to be supported by the housing parts when the latter are assembled together and secured by rivets. The blade 29 is riveted at 30 to support 25, apertured at 32, 33 to give resilience, and formed with a bowed compression member 35 which engages a notch in part 39 of support 25 so as to assist the resilience of the blade in biasing the latter into the position shown in Fig. 2. When the plunger 17 is depressed against the hump 40 on support 25, the blade snaps over against the other contact member, and returns automatically when the plunger is released. The plunger may be actuated by a handle or pedal 68 on a member 70 having an enlarged end 73 which is trapped in recesses 74 in the housing parts when the latter are assembled. Reference has been directed by the Comptroller to Specification 779,424.
