Abstract
590,581. Electromagnetic interrupters. PLESSEY CO., Ltd. (Mallory & Co., Inc., P. R.). Feb. 9, 1945, No. 3350. [Class 38 (v)] In an electromagnetic vibratory interrupter, the armature 13 is carried on the lower end 42 of a rigid plate 35 (Fig. 6) which is fixed, by screws passing through holes 49 and 46, to two spring strips 48 (Fig. 8) fixed at 47 to a contactcarrying stack. The stack consists of a series of spacing members which clamp between them two pairs of springs carrying the fixed contacts 31, 33. The centre part 44 of the plate 35 passes through a hole in the stack and the upper end of the plate carries contacts 38, 39 which co-operate with the fixed contacts. The interrupter may be mounted in a casing which provides electrical shielding, a felt ring at the top and a rubber ring round the operating coil affording a resilient mounting.
