Abstract
The relay of the present invention is economically adapted for nuclear and commercial applications. The reliability of the relay is enhanced by utilizing a split coil and a permanent magnet located therebetween. The so-called split coil/permanent magnet configuration supplements the upward forces generated by a kickout spring by positioning a permanent magnet so as to assist in holding the armature and contacts rigidly in the off position. The design of the present invention assures that the armature stays in the desired position even when the relay is subjected to shock and vibration forces present in the environment.
