The electrically-operated rotary shutter is particularly adapted for remote control operation and especially for use on space vehicles, so that the shutter may be automatically operated by controls carried by the spacecraft or by signals sent from a ground station. The shutter is normally closed and is moved by a solenoid, on command, to an open position. It is closed by spring action.
