Abstract

652,639. Press-button retractive switches. IGRANIC ELECTRIC CO, Ltd. Jan. 20, 1948, No. 1733. Convention date, Jan. 20, 1947: [Class 38(v)] A snap-action switch comprises a blade spring 1 having contacts 12 on integral contact arms 13 connected at 15 to U-shaped flipper arms 14, which are connected at their closed ends to arms 16 engaging notches in a push-button 9. On depression of the latter, the contact pressure is increased until the. dead-centre position is reached, the spring then snapping over to close contacts 7, 12 and being restored, on release of button 9, by a spring 19. In a modification, Fig. 7, the spring carries one contact 23, the contact arms 29 being mounted on a block 24 which also carries the operating arm 32. Operation is effected by a press-button and return spring, bearing respectively against the upper and lower face of the arm 32.
