This is TPS is a variable type resistor.This type of TPS works by varying a set voltage being *read* by the ECU at different points on the resistor. At WOT there is less resistance and so there is more voltage. At idle there is the most resistance, and so the least voltage.
As this TPS is a switch, at the set resistance the circuit will change to the circuit specified to that resistance.
i like your pictures and graphs, why does the switch type change voltage? what other things does the ECU do with this knowledge
