Abstract
An actuator for selectively actuating a circular array of electric switches. The actuator includes a molded plastic rotor part that contains particles of magnetic material. One portion of the rotor is magnetized to provide a permanent magnet that is effective to attract a switch actuating arm that is pivoted to the rotor. Another tubular portion of the rotor is magnetized to provide the rotor of an electric stepper motor. The stepper motor rotates the rotor to various positions. The arm can be attracted by an electromagnet and pivoted to a position in which it operates one of the circular array of switches.
