Abstract: A multi-directional output device includes a printed circuit board on which first and second magnetic sensors are arranged, and a direction control unit arranged above the printed circuit board. The direction control unit includes first and second rotary driving bodies, first and second magnets, a shaft stick, a balance washer, and an annular spring, wherein the first and second rotary driving bodies are each a rotatable elongated arc-shaped structure. The first and second magnets are respectively fixed on one end of the first rotary driving body and one end of the second rotary driving body. The balance washer is disposed below the shaft stick and in contact with the first and second rotary driving bodies. The annular spring is arranged under the balance washer and in contact with the balance washer. The first and second magnetic sensors are arranged to correspond to the first and second magnets, respectively.

Abstract: An encoder with a light emitting diode includes: a light emitting diode, a switch module, an encoder module and a control shaft. The switch module includes an insulating base having a terminal part, a conductive elastic piece and a pressing driving body. The conductive elastic piece is disposed in the insulating base, and is disposed above the terminal part. The pressing driving body is disposed in the insulating base and is disposed above the conductive elastic piece for accommodating the light emitting diode. At least part of the encoder module is disposed in the insulating base, and the encoder module includes a magnetic sensor, a magnetic ring and a rotating driving body. The control shaft passes through a penetration hole of the rotating driving body, and is disposed above the pressing driving body.

Abstract: A sliding variable resistor includes a sliding base, a first supporting pole, two buffering members, a substrate, a casing assembly, an anchoring plate, a driving member, a driven member, a belt, and a belt guard. The sliding base includes two first through hole and at least one variable resistor sheet. The first supporting pole is inserted into the two first through hole. The first supporting pole has its two ends abut against the first buffering seats, respectively. The substrate is engaged with the two buffering members. The two buffering members are arranged in the casing assembly. The anchoring plate is fixedly arranged on the casing assembly. The belt is engaged with the driving member and the driven member, respectively. The belt guard is fastened to the sliding base, and is engaged with the belt. As such, the sliding base, while sliding, can have an improved smoothness.
