Abrégé

A switch assembly for adapting a non-contact switch into a contact triggered switch, such that the internal electrical state of the non-contact switch can be triggered by mechanical contact with an object or surface. The switch assembly can include an adapter body coupled to the non- contact switch and an actuation body coupled to the adapter body. The actuation body can be movable relative to the adapter body to selectively position a target supported by the actuation body within a sensing region of the non-contact switch. The actuation body can be moved by an external object making contact with a portion of the actuation body.

Actuation apparatus for use with magnetically-triggered proximity switches are described herein. An example apparatus includes an actuator shaft (116) having a first segment (168) and a second segment (170), the first segment intersecting the second segment. The first segment (168) defines a first end (172) of the actuator shaft, and the second segment (170) defines a second end (174) of the actuator shaft opposite the first end. The second segment further defines a slot (178). The apparatus further includes a detector magnet assembly (120) coupled to the first segment (168) of the actuator shaft (116) adjacent the first end (172). The apparatus further includes a switch arm (114) coupled to the second segment 170 of the actuator shaft (116). The switch arm (114) includes a first end, a second end opposite the first end, and a portion located between the first and second ends of the switch arm. The portion of the switch arm (114) is positioned in the (slot (178) of the actuator shaft.

Abrégé

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.
