Abstract
Abstract Reed relays, both normally closed and normally open circuits, are disclosed as comprising a novel switch section, a bobbin section and a coil means wound on the bobbin section. The switch section and bobbin section can be manufactured independently and thereafter assembled so as to reduce manufacturing costs, facilitate calibration and expedite assembly. The reed relay is structured to provide a total shield around the reed elements to eliminate the effect of random environmental magnetic fields.
