Abstract:
The instant invention teaches a monostable shutter with magnetic blade return using a bistable actuator with blade motion constrained to provide drive force in a single direction and permits the use of compact bistable coil for continuous use by a circuit that applies a high voltage at the beginning of drive that decays to a lower voltage to prevent coil burn out.
