Abstract

1419409 Electromagnetic contactors WESTINGHOUSE ELECTRIC CORP 16 April 1973 [24 April 1972] 18233/73 Heading H1N Two contactors 14, 16 are mounted side-byside on a base 70 with an interlock member 22 between them and supported at the base 70 for pivotal movement on engagement of either of its beveled edges 46, 48 by a respective movable member 42 of one contactor into the path of movement of the movable member 42 of the other contactor to prevent simultaneous operation thereof. The interlock member 22 is pivoted on a pin 28 on a bracket 20 secured to the base 70.
