Reed relays use an electromagnetic coil to directly control one or more flexible ferromagnetic metal reed switches, eliminating the need for a mechanical armature. Reed relays require low coil current and are capable of fast operate and release times. Dual coils in some reed relays allow for latching capability. Contact forms include DPDT, DPST, SPDT and SPST.
