Abstract

Preferred embodiments of the present magnetic locking system can be used for releasably locking a first component to a second component. In one embodiment, the locking system includes a ferro-magnetic member associated with the first component, where the ferro-magnetic member is made of a ferro-magnetic material, and a housing attached to the second component and positioned adjacent to the ferro-magnetic member. Preferably, the housing includes first and second blocks that sandwich an intermediate block. Further, the first and second blocks are each preferably made of a ferro-magnetic material and the intermediate block is made of a non-ferro-magnetic material. Additionally, there is also an aperture formed within the housing, with a permanent magnet rotatably seated within the aperture. The magnetic locking system preferably includes a switch mechanism that is operatively connected to one of the permanent magnet and the housing, wherein the switch mechanism is configured and arranged to rotate the housing and the permanent magnet relative to each other between an 'on' position and an 'off' position.
