Abstract
A turn angle indicator or angular displacement indicator and, more particularly, relates to a capacitive turn angle indicator, especially a positioning sensor for a flap or throttle valve, including a supporting plate fastened to the apparatus at a close narrow distance in front of a further supporting plate which is rotatable planar-parallel relative thereto and which is utilized for a mutually oppositely located narrow spoke or sector-shaped electrode pattern, and with a bearing structure for the rotatable supporting plate and which is fastened to the apparatus. The supporting plates are guided relative to each other through the intermediary of compressively-loaded distance spacers which are arranged in the region of the outer edges of the plates which extend in parallel with the axis of rotation of the rotatable plate.
