Abstract

697,068. Snap-action switches. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Nov. 20, 1951 [Jan. 13, 1951], No. 27197/51. Class 38 (v) [Also in Group XL (c)] A high frequency wave band switching arrangement (see Group XL (c)) comprises a number of wafer switches 82, 85, 90, 94 having a common shaft 75 rotated into either of two positions by a toggle mechanism. This mechanism comprises an arm 72 on a shaft operated by a control knob the forked end of the arm engaging a projection on an arm 74 attached to the shaft 75. A spring 78 provides the snap action, and stops 80, 81 limit the travel of the arms.
