ABSTRACT:
A single-turn miniature potentiometer includes a first substrate having an annular conductive track formed thereon and a second substrate facing the first and having an annular resistive track formed thereon. An insulating layer is placed between the two substrates and has an opening provided therein for receiving a disk-like rotor which bears an electrically conductive wiper for simultaneously contacting both the conductive and resistive tracks. Electrical connections are made between the resistive and conductive tracks by means of external U-shaped clips.
