An electrical assembly including a conductor arrangement and a dual resolution potentiometer electrically connected to the conductor arrangement. The dual resolution potentiometer includes a first resistive element having a first adjustment mechanism and a second resistive element having a second adjustment mechanism. The first adjustment mechanism being coupled in a hysteresis arrangement to the second adjustment mechanism.

A high reliability variable resistor device for extending the lifetime of the potentiometer includes a substrate that is electrically insulative. The substrate is installed within a control circuit having a control switch. A wiper movably coupled to the substrate is electrically conductive. A resistive material and a conductive common trace are coupled to the substrate. An array of taps electrically coupled to the resistive material extends perpendicularly outward toward the common trace. The wiper contacts at least one of the array of taps while being spaced from the resistive material. The wiper moves across the array of taps and the common trace when the wiper moves along the substrate in response to actuation of the control switch. The spacing of the array of taps along the resistive material forms a series of resistive changes that adjusts a setting of the control circuit.
