Abstract
An oral irrigator including a reservoir, a handle, a housing, a bezel positioned at least partially within and secured to the housing, and an actuator operably coupled to the housing and movable relative thereto is disclosed. The actuator includes a control shaft extending from the interior surface of the face and positioned inwards from an outer perimeter of front wall. The control shaft extends through an aperture in the housing and movement of a gripping body causes the control shaft to directly actuate a switch or a pressure assembly positioned within the housing. The actuator also includes an augmentation fluid positioned between the bezel and a portion of the actuator. The augmentation fluid modifies a frictional relationship between the bezel and the actuator to provide a predefined resistance force between the actuator and the bezel as the actuator is rotated relative to the bezel.
