Abstract

548,162. Electromagnetic interrupters. TELEFONAKTIEBOLAGET L. M. ERICSSON. Dec. 9, 1941, No. 15893. Convention date, Nov. 16, 1940. [Class 38 (v)] In a self-interrupter for driving a selector 13 or other switch, the armature 11 carries a pin 18 which passes with some clearance through a hole in a lever 15, and the end of the lever engages a projection 24 on a contact spring moving this sideways out of engagement with a co-operating contact spring.
