Abstract

1304233 Electromagnetic relays WESTERN ELECTRIC CO Inc 12 Aug 1970 [13 Aug 1969] 38799/70 Heading H1N An electromagnetic relay has pole faces of the armature and yoke and a core member arranged so that co-operating faces are of different sizes in order that the inwardly bowed faces, produced by plating of corrosion resistant and hard wearing materials on the pole faces, shall not produce too large an effective air gap in the magnetic circuit. Fig. 5 shows an armature and core arrangement allowing for dished faces on a remanent relay of the type shown in Fig. 1.
