Abstract

1. A device for detecting at least one given position of a rotary element (2) comprising, disposed in a sealed housing (12, 13), a finger member (21) fixed to said rotary element and carrying at least one magnet (25a, 25b; 31) and at least one switch (17a, 17b; 32, 33) having a flexible blade, controlled by a magnet and having an elongated shape defining two ends, this switch being disposed in a closed casing and arranged to be selectively closed and opened as a function of the position of the magnet, characterised in that the rotary element (2), the finger member (21) and the magnet (25a, 25b; 31) moving in accordance with a given angle (alpha), the switch (17a, 17b; 32, 33) is located mainly outside the angle swept through by the magnet and only an end part of the switch is located in confronting relation to the magnet when the latter occupies a position corresponding to the given position of the rotary element.
