Abstract

848,000. Push button switches; momentary contact switches. FRACHON, M. March 11, 1959 [March 19, 1958], No. 8343/59. Class 38 (5). A switch operable by a push rod 4 e.g. for limit switching has a cam plate 17 moving a microswitch 11 away from an adjustable abutment 20 against pressure from a spring 12. The abutment 20 preferably takes the form of a snail cam and is adjustably rotated to determine the exact point in the stroke of rod 4 when the microswitch push button 23 is released to actuate the switch. The cam 17 can be contoured to obtain a momentary contact action during the stroke and the return stroke can be made non-effective by suitably pivoting the cam plate 17.
