Magnasphere Special Purpose Pull Apart Switch Set

Magnasphere’s  patented technology utilizes the principal of Spherical Magnetism. The heart of the switch is a magnetic sphere, or ball contact. This sphere is housed in a durable metal housing. Completing the switch is a seal that contains the contacting electrode, insulated from the magnetic perimeter by a time proven ceramic to metal bond. The case or seal provides the second contact point required to complete the electrical circuit. The seal/electrode cap is welded to the housing in an inert atmosphere providing a hermetically sealed contact.

PRINCIPLES OF SPHERICAL MAGNETISM: Finite element analysis shows magnetic flux paths of the Magnasphere's magnetic ball contact. The spherical shape is not polarity sensitive and will be attracted to either pole of the actuating magnet

Installation Instructions

The Magnasphere Special Purpose Pull Apart Switch Set has three parts: the switch probe, the switch receptacle and the magnet. The MS4702-A is designed for use when standard surface mount security switches won’t work due to swinging gates, free moving objects, vehicle protection, worn gates/doors or expanding metal curtains. Now you can protect products and property that is kept outdoors such as recreation vehicles, golf carts, lawn mowers, ladders, truck tractor trailer, motor boats, ATV’s or a host of rental equipment. To use the Pull Apart, attach the probe receptacle to a solid surface and anchor it well. Position the receptacle and switch probe so that the probe can pull out of the receptacle easily. Don’t connect it at a right angle or upside down. This will delay and/or alter the switch’s ability to react to tampering and theft. Connect the appropriate zone from the alarm panel to the switch probe. Thread the armored cable through the item to be protected and insert the probe into the receptacle.
