  • Electronic switching arrangement
    Patent number: 5428496
    Abstract: An electronic switching arrangement for controlling a coil includes a capacitor for energizing the coil by momentarily passing a current therethrough so as to generate a required attractive force for movement of the armature. After movement of the armature, only a lower holding current is supplied. Arranged parallel to the coil is a voltage divider which cooperates with a transistor to detect and evaluate an unintentional movement of the armature.
