Abstract
Magnetic orientation-independent magnetically actuated switches may be made by producing an outer cylinder and an actuator cylinder from ferromagnetic sheets and non-ferromagnetic sheets in alternating order. A first ferromagnetic body is attached to an end of the outer cylinder. The actuator cylinder is positioned within a first bore of the outer cylinder, the actuator pin is positioned within a second bore of the actuator cylinder and a third bore of the first ferromagnetic body with a portion of the actuator pin extending beyond the third bore of the first ferromagnetic body. A second ferromagnetic body is attached to the portion of the actuator pin, thus forming the magnetic orientation-independent magnetically operated switch.
