An electrical assembly including a conductor arrangement and a multi-resolution potentiometer electrically connected to the conductor arrangement. The multi-resolution potentiometer includes a first resistive element having a first adjustment mechanism and a first wiper, and a second resistive element having a second adjustment mechanism and a second wiper. The first adjustment mechanism is coupled in a hysteresis arrangement to the second adjustment mechanism. A resistor network provides an electrical output for the potentiometer and electrically couples the first wiper with the second wiper.

A resistor trimming device comprising a resistor trimming unit is provided, which divides a single one adjustable resistor string into a plurality of adjustable resistor string groups, so that a resistance of the parallel resistor faced by a switch can be effectively reduced, and a design of the on-resistance and off-resistance of the switch can comply with a general design rule. In addition, the resistor trimming device provided further comprises a decoder. When trimming the overall resistance of an electronic device, a user can directly input a binary code or an original thermometer code used in the adjustable resistor string being not grouped, without knowing an encoding manner, and then, the decoder generates a trimming thermometer code and a group code to control a main switch and switches in the multiple adjustable resistor string groups being the grouped from the adjustable resistor string.
