Positioning arrangement and method

摘要

The arrangement includes first and second patterns such as photolithographic patterns of electrically conductive indicia provided on respective first and second surfaces of the components to be positioned. The patterns are adapted for relative movement in sliding contact relationship along the positioning axis. The patterns of electrically conductive indicia define electrically conductive pads at least one of which reaches the condition of being either open or closed when the surfaces on which the patterns are provided reach a given position along the positioning axis. Sensing is preferably effected by means of an amperometer.
