Latching Form B Reed Relays Overview Slide 6

To configure the reed switch in the normally closed state, a permanent magnet is required and mounted directly to the reed switch, both of which are internal to the actuating coil. The normally closed state is achieved by adjusting the magnetic strength of the magnet for proper operation. Proper magnet adjustment is achieved when the magnet will suitably close the contacts but still allow them to re-open once coil power is applied. Once this is achieved, the reed switch will remain in the closed state with no external power applied to the relay. Therefore, the relays can stay in the closed state never drawing any power for long periods of time.
