Variable resistor with light emitting element

A variable resistor with a light emitting element, comprising:

• a circuit board, extending in a longitudinal direction, having a circuit arrangement surface, a resistive circuit and a power being arranged on the circuit arrangement surface;
• a housing, fixed to the circuit board so as to form therebetween an internal slide space extending in the longitudinal direction, further having a sliding slot extending in the longitudinal direction, the sliding slot being communicative in space with the slide space;
• and
• a slide assembly, including:
• a slidable member, movable in the longitudinal direction in the slide space, having a light-emitting element mounting surface and a brush mounting surface, the light-emitting element mounting surface facing the sliding slot, the brush mounting surface facing the circuit board, the slidable member further including a light-emitting element accommodating groove located at the light-emitting element mounting surface by closing to the sliding slot;
• a fader set, fixed at the slidable member, penetrating the sliding slot;
• a light emitting element, disposed in the light-emitting element accommodating groove, being to project a light beam toward the fader set;
• a resistive circuit brush, disposed on the brush mounting surface, electrically connected with the resistive circuit;
• and
• two light-emitting element brushes, disposed on the brush mounting surface, being to electrically bridge the power circuit and the light emitting element;
• wherein, when the slidable member displaces in the longitudinal direction, the light emitting element continuously emits the light beam.
