An actuation assembly for an oral irrigator includes a bezel secured to or formed as part of a housing of the oral irrigator, an actuator operably connected to the bezel and moveable relative thereto, and an augmentation fluid positioned between the bezel and 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.

A knob assembly includes a first housing with a sidewall extending from a base and a retention member inwardly extends from the sidewall. An operable second housing includes a selective stopper selectively movable between a first position and a second position relative to the retention member. The operable second housing is further axially operable between a compressed position and an extended position relative to the first housing, and the operable second housing includes a biasing member.

A control apparatus includes a main body unit, a plurality of moving members each of which is movably supported by the main body unit, a magneto rheological fluid provided between the main body unit and each of the plurality of moving members or between each of the plurality of moving members, and one magnetic field generator configured to apply a magnetic field to the magneto rheological fluid.

A lever switch device includes a shaft member, a rotary operation member, a push switch, and a flexible board. The flexible board has a first board part, a first wiring part connected to the first board part, a second board part, a second wiring part connected to the second board part, and an integrated wiring part. The first board part has a fixed contact. A movable contact of the rotary operation member comes into contact with and separates from the fixed contact in response to a positional shift of the rotary operation member. The second board part receives a signal output from the push switch. The integrated wiring part is at a position away from the first board part and the second board part, and a part of the first wiring part and a part of the second wiring part are integrated in the integrated wiring part.
