ARMATURE/ACTUATOR FOR A RELAY

摘要

A method of constructing an encapsulated relay is described in which the relay includes an intensely magnetised actuator/armature formed from a chromium/cobalt/iron alloy after fabrication is assembled and encapsulated in a clean environment before being magnetised and heat treated. A relay construction which includes such an actuator/armature is described in which the relay components are accurately located on an insulating base which itself is moulded out of a sheet of conductive material so as to leave protruding lugs which can be bent upwardly and downwardly to form (or provide supports for) some of the component parts of the relay.
