摘要
A switch is mounted in a housing (1) of a high-intensity static magnetic field generator and the housing (1) includes a rotation shaft (10) supported on the housing, a coil mounted relative to rotation shaft (10), arms (80, 90) energized by coil (20), a rod (70) energized by the arms (80, 90) latching/snapping elements (91, 92) energized by the arms (80, 90), a rod (70) moved by the elements (91, 92) and a movable electrode plate (50) energized by rod (70) and movable into and out of engagement with fixed electrode plates (30, 40) 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 (20) under a mutual electromagnetic atmosphere resulting from electric current in the coil (20) and high magnetic field of the high-intensity static magnetic field generator, the elements (91, 92) 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 plates (30, 40). It is also possible to hold the opened and closed states.
