Abstract

723,032. Retractive switches. LONDEX, Ltd., and STERN, W. L. March 27, 1953 [April 8, 1952], No. 8951/52. Class 38 (5). A limit switch has a slidable actuating member 11 controlled by, e.g. a machine tool, and having a cam surface 16 engageable with an operating member 5 which is pivoted at 8 and carries two mercury switches 1, 2 which are thus operated by movement of member 11 which has a surface 17 to keep the switches operated even if it overshoots. The switches are supported by plates 3, 4 adjustably secured to the member 5 at 6 and 7. Push-button or other switches having an actuating member operable by the member 5 may replace the mercury switches.
