A variable attenuator comprises a generally horseshoe-shaped main resistance element, a sliding member movable thereover, and a bypass provided around that portion of the main resistance element adjacent the end portion of the path of said sliding member. The bypass is made of a conductive element or conductive element and a resistance element, the amount of current flowing through said bypass being thereby increased to enable a maximum attenuation.
