The invention relates to an electronic circuit arrangement for driving a coil. A current flow is briefly produced in the coil with the aid of a capacitor, which current provides the switching magnet of the coil with the necessary force for attraction. Once the magnet has been attracted it is then only still supplied with a lower holding current. Connected in parallel with the coil is a voltage divider which interacts with a transistor and is able to detect accidental movement of the armature of the magnet system of the coil and to evaluate said movement automatically. <IMAGE> |
