The invention is characterised in comprising means (188), for measuring the current flowing through the contacts (22a, 22b, 23a, 23b). Such a unit does not require a position sensor for the leaf of the door. The invention further relates to a method for determining the state of the door leaf, comprising the following steps: supply of a circuit comprising the electrical contacts (22a, 22b, 23a, 23b) and measuring the current flowing through said circuit.</p> |
