Abstract: A magnetic switch includes a substrate having a recess therein. A rotor or rotors are provided on the substrate. The rotor includes a tail portion that overlies the recess, and a head portion that extends on the substrate outside the recess. The rotor may be fabricated from ferromagnetic material, and is configured to rotate the tail in the recess in response to a changed magnetic field. First and second magnetic switch contacts also are provided that are configured to make or break electrical connection between one another in response to rotation of the tail in the recess, in response to the changed magnetic field. Related operation and fabrication methods also are described.
