Abstract:
An indicator system, comprising:a resistor card having thereon an arc-shaped resistive path comprising a sot of spaced apart conductor lines and an arc-shaped resistor trace, said resistor trace having an arcuate center and overlying said set of conductor lines, each conductor line extending from within said trace to a common pivot point and at a non-zero angle with respect to a radial line drawn from said arcuate center; anda wiper assembly including an arm having a plurality of parallel fingers extending from one end so that one of said fingers on said arm engages a first conductor line adjacent said resistor trace and a second finger on said arm engages a second conductor line adjacent said resistor trace, said second conductor line being adjacent said first conductor line, said wiper assembly providing rotational movement of said fingers along said arc-shaped resistive path such that said second finger conductively contacts said second conductor line before said first finger breaks conductive contact with said first conductor line.
