A capacitive sensor for printed circuit boards and an set made of capacitive sensor and a printed circuit board

The invention concerns a capacitive sensor (1) for printed circuit boards (7), containing a platform (2) for sensing the presence of an element across an insulating sheet. The platform (2) is articulated to at least one elastically deformable support (3), adapted for fastening to a printed circuit board (7) in order to hold the platform (2) above this printed circuit board (7). An edge clip (4) is formed at the free end of one support (3), which is used for seating on an edge segment of the printed circuit board (7). The edge clip (4) has a boundary wall (4a) and, connected to it, a first clamping part (4b) and a second clamping part (4c), opposite each other. The invention also concerns a set made up of a capacitive sensor (1) and a printed circuit board (7), which contains printed circuit tracks (9) situated on at least one surface of the printed circuit board (7), in which one of the first clamping part (4b) and the second clamping part (4c) of the clip (4) of the capacitive sensor (1) forms an electrical contact with a printed circuit track (9) situated on the selected surface of the printed circuit board (7).
