Abstract

442,079. Snap - action switches. NORTON, F. D., 6, High Street, Cheadle, Cheshire, and STUART, J. F. W., 30, St. Ann Street, Manchester. July 28, 1934, No. 22059. [Class 38 (v)] [See also Group XXXVIII] Road-traffic signal lights are controlled by a motor-driven, time-switch which is provided with a latch r<2> adapted to cooperate with stops v. The motor operates the switch through a spring and an eccentric cam g on the motor shaft moves the latch r<2> radially to effect its release and allow snap action of the switch under spring control.
