摘要:
The capacitive sensor for detecting a relative movement of two adjacent bodies comprises a first electrode (76), which has a first electrically conducting electrode surface (78) and which is arranged on a first electrode supporting body (74), and a second electrode (86), which is opposite the first electrode (76), has a second electrically conducting electrode surface (88) and is arranged on a second electrode supporting body (82). The second electrode supporting body (82) is designed as a resilient film element (84) that is supported on the first electrode supporting body (74) on two spaced-apart opposing support sections (96) on both sides of the two electrodes (76, 86). The capacitive sensor further comprises a pressure body (92) on the side of the electrode supporting body (82) facing away from the second electrode (86). Said pressure body (92) comprises at least two pressure projections (94) that rest, in the region between the support sections (96) of the second electrode supporting body (82), against the side of the second electrode supporting body facing away from the second electrode (86) and that press against the second electrode supporting body (82) while bending it when there is a relative movement between the first electrode supporting body (74)and the second pressure body (92). The at least two pressure projections (94) are spaced apart from each other in the same spatial direction in which the support sections (96) of the second electrode supporting body (82) are spaced apart. The second electrode (86) is secured to the second electrode supporting body (82) only in a securing section that is substantially in the center between the pressure regions of the second electrode supporting body (82) in which the pressure projections (94) rest against the second electrode supporting body (82).
