A variable resistor with a light emitting element includes a circuit board, a housing and a slide assembly. The circuit board extending in a longitudinal direction has a circuit arrangement surface to arrange thereon a resistive circuit and a power circuit. The housing fixed to the circuit board so as to form a slide space has a sliding slot extending in the longitudinal direction. The slide assembly further includes a slidable member, a fader set, a light emitting element, a resistive circuit brush and two light-emitting element brushes. The fader set fixed at the slidable member penetrates the sliding slot. The light emitting element in an accommodating groove of the slidable member projects a light beam toward the fader set. The resistive circuit brush electrically connects the resistive circuit. The two light-emitting element brushes electrically bridge the power circuit and the light emitting element.

A position sensor includes a variable capacitor assembly and a circuit board. The variable capacitor assembly includes a baseboard and a dielectric coupling element. The baseboard includes a baseboard body, a grounding electrode and two power electrodes. The grounding electrode is disposed nearby one side of the baseboard body. The two power electrodes are disposed separately near the other side of the baseboard body. The dielectric coupling element is spaced with the two power electrodes and the grounding electrode, and operable to be moved along a moving path. A covering condition is varied when the dielectric coupling element is operated to move along the moving path. When a power is alternatively applied to the power electrodes, a pair of capacitance values between the grounding electrode and the power electrodes is varied with the covering condition to accordingly determine a relative position of the coupling element along the moving path.
