Abstract
A switch is mounted in a housing of a high-intensity static magnetic field generator and the housing includes a rotation shaft supported on the housing, a coil mounted relative to rotation shaft, an arm energized by the coil, arm energized by that arm, a rod energized by the arm, a latching/snapping element energized by the rod, a rod moved by the element and a movable electrode plate energized by the rod and movable into and out of engagement with a fixed electrode plate and holding their engaged and disengaged states. Almost every member of the switch is made of non-magnetic material, such as plastics and copper. Upon driving the coil under a mutual electromagnetic atmosphere resulting from electric current in the coil and high magnetic field Bo of the high-intensity static magnetic field generator, the element can open and close an associated electric circuit, while performing a latching/snapping operation, which is included in the high-intensity static magnetic field generator connected to the fixed electrode plate. It is also possible to hold the opened and closed states.
