Abstract

912,948. Switches held set and freed mechanically. COQ, N. V. June 22, 1961 [July 2, 1960], No. 22676/61. Class 38 (5). In a switch similar to that of Specification 753,754, operation of the opening button 33a is prevented unless the opening spring 9 is tensioned and the switch is closed. Similarly, operation of a closing button 40 is prevented unless the closing spring 14 is tensioned. The button 33a acts to release a spring biased lever 28, movement of which to open the switch is prevented by links 41 ... 43 unless the contacts are closed. The button 40 likewise acts to release a lever 34, movement of which to close the switch is prevented by links 46...48 unless the spring 14 is strained and an intermediate member 10 connected thereto is latched at 26, 27. The member 10 is moved to its latched position to tension the springs by a piston 17.
