The band includes means for mechanically engaging a surface of an aperture in the face plate such that the housing is secured within the aperture. Preferably, the potentiometer also includes a stop means that engages a shoulder or surface of the face plate of the hearing aid positioning the potentiometer within the aperture a selected distance such that the knob of the potentiometer extends beyond a front surface of the face plate.
