Abstract
545,536. Mechanical switches without quick action combined with valves; indicators. MASCHINENFABRIK OERLIKON. Dec. 4, 1940, No. 17277. Convention date, Nov. 6, 1939. [Class 3S(v)] A combined switch and valve assembly in which, the valves control for example a distant switch 15, Fig. 3, the position of which is indicated, electrically, comprises a sleeve 1 adapted to be secured to the switchboard; a sleeve 3 which may be rotated and depressed within the sleeve 1 and which carries a handle 2 and a movable contact 4, a. lamp 5 within the handle and a valve assembly 6 which may be clamped to the sleeve 1. The rotation of the handle 2 moves the contact 4 into one of two positions, and depression of the handle 2 operates one of two valves 6 by means of a projection 8, the particular valve selected depending on the rotary position of the handle. In the arrangement of Fig. 3, the lamp 5 only lights up when the position of the switch 15 does not correspond with that of the switch 4. As shown, the lamp 5 is out, and the handle 2 will indicate " off " since the switch 15 is " off." If now the handle 2 is turned to its other position, the lamp 5 will light up till depression of the handle has operated a valve to cause pressure fluid to close the switch 15 and with it an auxiliary switch 17 in the lamp circuit.
