Abstract

892,650. Interrupters. WILKINS & MITCHELL Ltd., and WILKINS, E. W. Oct. 19, 1960 [Oct. 28, 1959], No. 36523/59. Class 38 (5). In a rotary cam limit switch assembly for controlling, e.g. a power press, and wherein individual switches are operated by cams 4 adjustable on a cam shaft 3, the switches 5 are secured to shoes 6 which are slidably mounted in circumferential slots 2 in a housing 1. Each shoe has a projection 10 entering one of the slots and two bearing faces 9 which engage the housing. A spring-loaded clamping nut 7 is screwed on to a pin 10 projecting from each shoe and forces two projections 15 of a washer 12 into apertures 16 in the shoe, thereby preventing rotation of the washer. Pointers 17 on each washer indicate the angular position of the switches. The switches are actuated in succession by cams 4 through cam followers 24.
