Abstract

1524289 Magnetic switches FELTEN & GUILLEAUME 19 Nov 1976 [2 Dec 1975] 48428/76 Heading H1N A holding magnet having a release coil 2 for energization to release an armature 3 for tripping a circuit-breaker (not shown) has a permanent magnet 1 across separated laminations 4, 5 which are normally bridged by the hose of the Y-shaped armature 3 whose other arms form knife edge pivots and is biased by a spring 7.
