ABSTRACT:
A magnetically actuated proximity device or switch is provided with an armature formed as a shallow U that is pivoted at its center and arranged with the legs of the U directed toward the pole faces of a pair of permanent magnets. The particular shape increases the sensitivity of the device and the force available for operating contacts or other output devices in response to the diversion of flux from an end of the armature.
