ABSTRACT:
A magnet system for a bi-stable relay includes a coil, first and second core yoke members, and an armature. The coil has a first polarity state and a second polarity state. Each of the first and second core yoke members has a core arm and a yoke arm. Each of the yoke arms of the first and second core yoke members has a pole face. The armature has substantially parallel armature core arms separated by a permanent magnet. The armature is pivotally mounted in an air gap between the pole faces of the yoke arms of the first and second core yoke members such that the armature core arms contact the yoke arms in a first switch position corresponding to the first polarity state and in a second switch position corresponding to the second polarity state. The armature core arms are arranged substantially perpendicular to a center axis of the coil.
