Abstract
Abstract An improved magnetic latching reed relay construction includes a hollow bobbin having an integrally formed flange and a base portion on each end. The bobbin is formed in one piece from a thermoplastic material. At least one reed switch is disposed within the bobbin. Mechanical support and electrical connections to the reed switch are provided by terminals disposed through each base portion so that they extend above the base portions. A plurality of terminals disposed through each base portion extend downwards therefrom to provide electrical connections to control coils wound about the bobbin.
