A control cover for a nerve stimulator is moveable between a protective position in which access to the stimulator controls is blocked to prevent accidental alteration of the settings thereof, except for emergency OFF button which remains accessible at all times and a use position in which the controls are accessible for intentional changing of control settings. The disclosed embodiment has a sliding panel which covers a set of keyboard switches. Apertures are provided in the cover and, in one position of the sliding cover, are aligned with the switches to permit access thereto. In the protective position of the cover, the apertures in the cover are moved out of alignment with the switches, preventing access thereto. The OFF switch and its corresponding aperture in the cover are larger than the other switches, so that it remains accessible in both positions of the cover.
