The Series FCB-205 relay is a polarized single-side stable design, where the flux from a permanent
magnet provides the armature holding force in the deactivated state, and its flux path is switched
and combined with the coil flux in the operated state. This results in appreciably increased contact
pressure in both states over that of a spring return nonpolar design. We also manufacture other
forms of the FCB relay:
FCB-405:
5 AMP 4PDT RELAY
FCB-310:
10 AMP 3PDT RELAY
