Abstract

550,975. Electromagnetic interrupters. PLESSEY CO., Ltd. (Mallory and Co., Inc., P. R.) April 13, 1942, No. 4858. [Class 38 (v)] In an electromagnetic interrupter self-alignment between co-operating contacts such as 18, 22 is secured by mounting one of the contacts, say, 18, on a tongue which can hinge about its supporting blade 14 the line of the hinging axis passing through the contact. The tongue may be produced by means of a V-shaped slot 15 in the blade 14. Specification 515,797 is referred to.
