Abstract

1,211,639. Actuation of switches; switch contacts. COMPAGNIE GENERALE D'ELECTRICITE. 27 May, 1968 [31 May, 1967], No. 25349/68. Addition to 1,064,163. Heading H1N. A switch of the kind described in the main Specification, in which the moving contacts 4 are held away from the fixed contacts 2 by a latching device 15 during the first part of the closing movement of ahandle 28 and then released near the end of the movement so as to be moved rapidly into engagement by the contact pressure spring 14 independently of the operating mechanism, has a plurality of parallel connected moving contact members 4 arranged to be moved successively into engagement with the fixed contacts 2. This may be achieved by using latch rollers 17 of different diameter or varying the surfaces 45 which the rollers engage or giving the member 4 different closing speeds such as by varying the strengths of springs 14 or giving the member 4 different moments of inertia.
