Abstract

1,136,123. Post office relays. TELEFONAKTIEBOLAGET L.M. ERICSSON. 10 March, 1966 [10 March, 1965], No. 10660/66. Heading H1N. The electromagnet of a Post Office Relay has its core end bent or otherwise offset from the core axis so that rotation of the core or its end adjusts the effective point of attraction of the pivoted or rotary armature 2 to set the sensitivity of the relay without changing the angle of armature movement.
