Abstract

1,210,618. Electromagnetic contactors. SQUARE D CO. 15 April, 1969 [6 May, 1968], No. 19209/69. Heading H1N. A heavy current electromagnetic switch is so designed that it may be assembled in either of two configurations providing respectively for normally closed and normally open operation and may readily be changed from one configuration to the other. It comprises a base 10; a magnetic frame 12 mountable in two positions (Figs. 2, 3 respectively) upon the base 10; a right angled contact carrying lever 17 pivoted to the frame; and an armature plate 16 which can be attached to either arm of lever 17 depending upon the position of frame 12. The base 10 and lever 17 are of moulded glassreinforced polyester. Pivoted to the lever 17 is a movable contact 36 urged by a pressure spring 32 towards a fixed contact 41 on the base. Contact 41 is connected through an arc blowout coil 44 to a terminal 42a. The coil has a core and cheeks 49; an arc-chute 54 is mounted between the cheeks and detachably retained by an extension 51a of an arc runner attached to the fixed contact 41. The lever 17 is pivoted on a pin 23 which is withdrawable, being retained by a spring clip (Figs. 7, 8, not shown). Besides repositioning frame 12 and armature 16 the coil 14, its core 15 and a biasing spring 29 must be replaced by similar members 65, 66, 64 respectively suited to the changed operating conditions; spring 64 is longer and stronger than spring 29.
