Abstract
856,945. Snap-action switches; press-button retractive switches. HAGGLUND & SONER A.B. Nov. 28, 1957 [Nov. 28, 1956], No. 37062/57. Class 38 (5). A blade 10 with contacts 18 at each end is connected to an actuating-member 16 by coupling members 12, 14, which are integral with the blade. Downward movement of the member 16 causes the coupling members to pass through a dead-centre position and snap the blade 10 upwards. The contacts may be restored by pushing upwards on member 16, or by a retractive spring (Fig. 4, not shown).
