ABSTRACT:
An electrical reed spring relay construction in which a single pair of reed springs are controlled to complete simultaneously two distinct conducting paths. A pair of yoke members each comprising a pair of parallel legs connected at one end by a transverse base member are suspended by the other ends of the legs at opposite ends of an encapsulating envelope. Between the legs of each yoke member is arranged a reed spring member also suspended at one end of the envelope. The yoke assemblies are suspended at the envelope ends so that the other ends and base members overlap and are spaced apart to present the contact gaps. Upon the application of a magnetic field, the other end of the reed spring member of each yoke member is urged into contact with the base member of the other yoke member. Two distinct conducting paths are thus completed between opposite ends of the envelope: one via the reed spring member lying between the legs of one yoke member and a leg of the other yoke member and the other via the reed spring member lying between the legs of the latter yoke member and a leg of the former yoke member. In a second embodiment, the terminal elements of each conducting path emerge at the same end of the envelope. The transverse base member of each yoke is interrupted and the reed springs are operative to make connections between the yoke member legs which form the conducting paths.
