Abstract

553,480. Actuation of switches; retractive switches. BLISS, CO., E. W. Sept. 15, 1942, No. 13003. Convention date, Oct. 28, 1941. [Class 38 (v)] A retractive switch 11 is operated by a cam 30, through an intermediate loosely-mounted member 32, the arrangement permitting a greater rotation of the cam than is necessary to operate the switch through spring accommodation on the button 12, so that the circular part of the cam can bear on the member 32. The cam is returned by a spring-pressed fork 41, the prongs of which bear on pins 51 on the upper surface of the cam 30.
