ABSTRACT:
A relay structure especially for miniature relays in which the armature part is held in place with respect to the electromagnet by means of shoulder pieces projecting within the relay housing. The housing and shoulder pieces may be made of a thermally softenable material, such as a "thermoplastic," so that the assembly may be heated and mechanically deformed to adjust clearances as a part of the final assembly process. Two versions of a flap or leaf spring for extra retention of the armature part are shown.
