Abstract
1,141,646. Latching switches. SQUARE D CO. 10 June, 1966 [20 July. 1965], No. 25871/66. Heading H1N. An interlock mechanism for preventing the simultaneous operation of a pair of electromagnetically operated switches 14, Fig. 1, comprises a pair of spring loaded plungers 52 projecting through apertures 34 in a common switch mounting 10 for engagement with switch actuating members 16 and alternately locked in position by engagement of a pair of rollers 78 in recesses 47 of fixed pair of arms 40. The rollers 78 are mounted on the free ends of short links 53 attached to the lower ends of the plungers 52 and are interconnected by a pair of cross links 41 whereby one pair of rollers 78 at one end is held in the recesses 47 by engagement of the pair of rollers 78 at the other end against substantially vertical faces 50 of the other fixed pair of arms 40.
