发明名称 DEVICE FOR INDICATING A POSITION
摘要 The invention relates to a device for indicating a position, a sensor supplying an electrical signal in dependence of the position of the device relative to a reference. According to the invention, the device is characterized in that it is provided with capacitors (C1, C2, C3, C4) which have fixed electrode plates (2, 11, 12, 13, 14) between which a common space (3) is present, while a body (4) of a dielectric material is present in the space (3) and is capable of moving in the space (3), so that the position can be derived from the location of the body (4) with respect to the electrode plates (2, 11, 12, 13, 14) of the individual capacitors (C1, C2, C3, C4). The capacitance values of the individual capacitors (C1, C2, C3, C4) vary as a function of the location of the body (4) in the space (3) between the electrode plates (2, 11, 12, 13, 14).
