A magnetically actuated proximity switch is provided with a double-pole double-throw contact arrangement. To substantially equalize the contact pressures between the two poles a movable armature, to which the movable contacts are firmly attached, is loosely pivoted to rotate about a transverse axis to open or close the contacts and to rock about a longitudinal axis to divide the available operating force between the two poles of the switch.

Double-pole double-throw proximity switch

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.
