大な悪影響を及ぼしていた。 Conventional variable resistors, especially trimmer type potentiometers, generally consist of a housing and a base, and are fixed to the lower part of a rotor on a resistor and current collector electrode formed on the surface of a flat substrate such as ceramic. In most cases, the resistance value was adjusted by pressing a slider with elasticity from above and sliding it. As a result, the slider moves together with the rotor, resulting in a single rotation system, making it difficult to finely adjust the resistance value. In addition, due to the wear of the resistor and slider due to contact friction between them, changes in resistance and noise increase as the number of rotations increases, resulting in lower cost and having a significant negative impact on the lifespan and reliability of the device.
