Abstract:
A potentiometric position sensor subassembly comprising an electrically insulating substrate, at least one arcuate resistive track formed thereon, a rotary member, at least one wiper member attached to the rotary member, and mutually engageable clip means formed on the substrate and the rotary member, the clip means being configured in such a way that when clipped together the wiper member contacts the track and the rotary member can be rotated about an axis substantially coincident with a center about which the arcuate track extends, wherein the clip means includes a circular resilient skirt which extends around at least part of a circle substantially centered on the axis about which the arcuate track extends, and the substrate includes a circular formation formed on or in a cylindrical surface thereof, the skirt including a series of individually resilient elongate fingers, each having at or near its free end a bead or groove, and the cylindrical surface having a corresponding groove or bead formed thereon into which the bead or groove on the fingers may resiliently engage.
