Abstract
A reed type relay comprises a frame forming a cavity and having coil terminals. A bobbin assembly containing a coil is mounted in the cavity, this assembly having a flange at each end. A pair of magnetic poles energized by a permanent magnet as well as by the coil is pressed into one of these flanges and the base end of a reed is pressed into the other. This reed is elongated and extends along the bobbin assembly with its tip located between the poles so as to be movable into engagement with each of them.
