We are building a solar car and we have a Spring loading Potentiometer we use as a pedal that connects up to a motor controller. Our current solution for switching to a hand pot was what is shown in the image. the problem of is that the switch does not let the resistance through the switch even when it is open. We are lost in terms of what to do now for a solution, is their switches that allow resistance through or is more complex solution necessary.

You need a single pole, double throw (SPDT) switch.
Like the circuit below but your pots connect where the lights are and the controller connects where the battery is shown.
