Magnasphere Miniature 3/8” Recessed Switch Set,  - 10 Pack

The recessed switch is designed for applications where a 3/8” press to fit set is needed, but space limitations will not allow for a full length set to be installed. Just 5/8” long, the installer is able to protect openings with the switch that otherwise would have to be secured with more visible surface mount configurations.

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.
