  • Rotatable variable resistor with clicking mechanism
    Patent number: 7042329
    Abstract: A rotatable variable resistor with a clicking mechanism includes a rotary unit provided with a rotor and a wiper, and a fixed unit provided with a cover, a resistor substrate, and external terminals. The wiper has an arm segment, a clicking projection and a non-clicking projection. The undersurface of the cover is provided with a clicking depression. The distance from the center of rotation of the rotary unit to the top of the clicking projection is different from the distance from the center of rotation to the top of the non-clicking projection. The non-clicking projection may have a flat top portion with a width extending in one direction that is greater than that of the clicking depression such that a sliding track of the top of the clicking projection is located within a sliding track of the non-clicking projection in the radius direction. The clicking depression may alternatively be an aperture.
