Abstract
A switching device is provided. An electromechanical switch controls rotation and/or lateral displacement of a core inside a housing with a magnetic field. The core is magnetically aligned by the magnetic relationship between the core and the housing. An energizing device generates a magnetic field that is sufficiently strong to realign the core with the generated magnetic field. As a result, the core switches to an energized state. When the generated magnetic field is removed, the core switches back to the natural state.
