Method and apparatus for attaching an electrical component to a printed circuit board. The apparatus includes a circuit board, an elastomeric connector, a rotary electrical component having a connector housing for holding the elastomeric connector, and one or more fasteners for securing the electrical component to the circuit board with sufficient force to compress the elastomeric connector and thereby ensure electrical contact between the electrical component and the printed circuit board.

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 rotary variable resistor includes a resistance circuit module, a fixation frame, a brush assembly and a rotor shaft. The resistance circuit module has a circuit board, an output circuit, three input circuits and a resistance ring. The output circuit includes a brush contact port having an annular brush contact area and an output port extending out from the brush contact port. Each input circuit has a resistor contact end and an input port. The three resistor contact ends are evenly annularly separated. The resistance ring co-axially and annularly spaced to the brush contact port contacts the resistor contact ends. The fixation frame is fixedly mounted on the resistance circuit module. The brush assembly rotatably restrained by the fixation frame bridges the annular brush contact area and the resistance ring. The rotor shaft for driving the brush assembly is connected with the brush assembly.
