Abstract: A potentiometer position switch circuit which includes a meter mechanism having a low friction potentiometer coupled to move therewith. The output of the low friction potentiometer is coupled together with the output of a set point potentiometer across the input terminals of a comparator. A magnetic latching double pole, double throw relay having set and reset relay coils is connected to the output of the comparator through the gate of a first voltage operated transistor and through sufficient resistance to minimize current drain and also through an invertor to the gate of a second voltage operated transistor and through a second resistor of sufficient resistance to minimize current drain. The output of the first voltage operated transistor is connected from a second voltage source through the set relay coil to ground and the output of the second voltage operated transistor is connected from a voltage source through said reset relay coil to ground.
