Abstract
997,854. Actuation of switches. AUTOMATIC ELECTRICAL CONTROL CO. Ltd. July 13, 1961 [April 13, 1960], No. 13120/60. Heading H2B. Two switches operated selectively according to the direction of rotation of a shaft 6 are mounted as shown on a base plate 1 such that their operating members 16, 19 extend respectively into the path of travel of insulating members 10 depending from the outer race 7b of a grease-packed ball or equivalnt bearing, the inner race of which is fast upon the shaft 6a. When the shaft 6a is stationary, contacts on pivoted members 16 and 19 are spring- urged against contacts on resilient blades 14a and 17 respectively, as shown. When shaft 6a rotates frictional drag on the bearing race 7b causes the appropriate member 10 to move the associated switch-operating member 16 or 19 and break the circuit with blade 14a or 17. As the speed of shaft 6a increases contact is made with resilient blade 14 or 17a. Straps 11 carry bolts 12 to act as stops preventing excessive strain on the switches at higher speeds of shaft 6a.
