An electrical switch for an electric machine includes body, a stator fixedly secured to the body and a rotor. The actuator includes a first member securable to the rotor and rotatable with it. The actuator also includes a second member, a first electrically conductive member cooperates with the second member. The actuator also includes a second electrically conductive member. The second electrically conductive member is spaced from said first electrically conductive member when said first electrically conductive member is in the first axial position and electrically engaged with said first electrically conductive member when said first electrically conductive member is in the second axial position.

A rotating device 1 according to the present application includes a motor 3, a gear 5 that transmits rotation of the motor 3 to an external device, and a sensor 7. The sensor 7 includes a sensor part 70 and a housing 72 that accommodates the sensor part 70. The sensor part 70 is capable of detecting a rotational speed or a rotational angle of the gear 5. The gear 5 includes a recess 50 in a rotational axis direction of the gear 5. The recess 50 accommodates a part of the housing 72.
