ABSTRACT:
An electrical reel spring relay construction in which the winding bobbin serves as the enclosing envelope. The bobbin has a longitudinal cavity therein, the cavity opening at each end of the bobbin in a tapered, wedge-shaped socket. Each spring member of the reed spring member pair has fitted thereabout near its terminal end a wedge-shaped sleeve dimensioned and formed to fit precisely in one of the cavity sockets. As so fitted, the spring members are positioned within the cavity so that their contact ends overlap. A contact gap spacing is determined by slightly oppositely angling the axes of the sockets from the longitudinal axis of the bobbin.
