Abstract

558,365. Swiches held set and freed mechanically. ROTAX, Ltd., and BOURNE, W. G. June 30, 1942, No. 9011. [Class 38 (v)] Contact arm f bearing contact g is actuated to make contact with contact e by a three armed lever h a plunger n engaging one arm j, another plunger o with sub-plunger s and spring bearing on another arm k, and a locking member u moved by the plunger o, ensuring that the plungers can only be operated by hand in one direction and alternately. A further pair or pairs of contacts may be closed by an additional lever 3 moving right or left from a central position, such lever only being operable when the plunger n is out and preventing, by its operation, any movement of the main switch while either of the additional circuits are closed, by placing a part 5a of a cylindrical extension in the path of movement of the arm j.
