Abstract
A magnetically-triggered proximity switch includes a cylindrical switch body and a first magnet non-movably secured within the switch body. The proximity switch also includes a pivoting cross arm. A second magnet may be movably disposed within the switch body, and the second magnet may be rigidly connected to the cross arm. When a magnetic target is not located within a specified range of the second magnet, the first magnet attracts the second magnet, thereby pivoting the cross arm into a first switch position and closing a first circuit. However, when the magnetic target is located within the specified range, the magnetic attraction between the target and the second magnet is greater than between the second magnet and the first magnet. The second magnet is displaced towards the target away from the first magnet, thereby pivoting the cross arm into a second switch position.
