Abstract
A capacitive sensor for detecting relative movement of adjacent bodies includes a first electrode on a first electrode supporting body, and a second electrode opposite the first electrode on a second electrode supporting body. The second electrode supporting body is a resilient film element supported on the first electrode supporting body by spaced-apart support sections. A pressure body includes two pressure projections that rest, in the region between the support sections, against the side of the second electrode supporting body facing away from the second electrode and that press against the second electrode supporting body while bending it when there is a relative movement between the first electrode supporting body and the second pressure body. The second electrode is secured to the second electrode supporting body only in a securing section substantially in the center between pressure regions at which the pressure projections rest against the second electrode supporting body.
