Abstract
A magnetically-triggered proximity switch includes a cylindrical switch body and a bias member non-movably secured within the switch body. The proximity switch also includes first and second normally-closed contacts and first and second normally-open contacts. The proximity switch further includes a spherical contact magnet disposed within the switch body, with the contact magnet being movable relative to the bias member from a first switch position and a second switch position. In the first switch position, an attraction to the bias member maintains the contact magnet in contact with the first and second normally- closed contacts, thereby completing a circuit between the first and second normally-closed contacts. In the second switch position, an attraction to a movable target external to the switch body moves the contact magnet into contact with the first and second normally-open contacts, thereby completing a circuit between the first and second normally-open contacts.
