ABSTRACT:
An electromagnetic actuator having an integral capacitor and secondary coil for reducing opening and closing response times without the need for switching circuits. The secondary coil produces a magnetic field during energization which aids the primary coil in opening the actuator. A capacitor progressively reduces the current flow through the secondary coil as it charges up. During deenergization, the capacitor discharges through the secondary coil, producing a magnetic field which opposes the primary coil's residual magnetic field and aids the closing of the actuator.
