An attenuator device is disclosed defined by an inner member having an outer cylindrical surface and a coaxial and relatively rotatable outer member having an inner cylindrical surface. Longitudinally extending grooves are defined in the respective surface of each member. Attenuating structure is disposed in the longitudinal length of the grooves of one of the members while bowed leaf springs are disposed in the longitudinal length of the grooves of the other member. The bowed leaf springs extend from the grooves of the other member to engage the grooves and attenuating structure of the one member to thus provide both detenting and grounding for the attenuator device.
