Abstract

906,990. Cam-operated switches; momentary contact switches; retractive switches. TELEMECANIQUE ELECTRIQUE. Aug. 31, 1959 [Sept. 11, 1958], No. 29667/59. Class 38 (5). An adaptable switch operated by an arm 13 has a cam 8 with e.g. four differing configurations, each of which can be positioned to control a micro-switch 2 via push-rod 4. The second cam 17 is reversible and engages rollers 16 fixed to the cam-shaft 21 such that the switch returns to a central position or alternatively to one of the two extreme positions in accordance with the position of the cam. By this means a large variety of operating conditions can be obtained.
