Abstract
A method for controlling the response time of an electromechanical device having an actuating solenoid comprising: applying three reference voltages from three reference voltage sources in a predetermined order to a voltage and current amplifier which drives the solenoid, generating from the three reference voltages three corresponding currents through the solenoid, the three currents being a premagnetization current, a maximum activation current of the solenoid and a deactivation current of the solenoid.
