A rotary electromagnetic actuator for car lamp low beam and high beam light switching device, comprises a shell (), a rotor (), a stator (), a rotating shaft () and an end cover (). The stator is fixedly installed in the shell to form a pair of arc-shaped stator magnetic poles () on which electric excitation can be applied; the rotor, as an arc-shaped permanent magnet, is fixed on the rotating shaft and is located in a magnetic field space of the arc-shaped magnetic poles of the stator; and the rotor is matched with the arc-shaped stator magnetic poles to form a closed magnetic circuit with an air gap (); two swing bars () are connected to two ends of the rotating shaft respectively.
