A HAIR CUTTING DEVICE

There is disclosed a drive unit (12) for a hair cutting device (10), the drive unit (12) being configured to receive a cutting unit comprising a follower element; the drive unit (12) comprising:a drive for driving a cutting unit mounted on the drive unit; an actuator (16) configured to cooperate with a cutting unit mounted on the drive unit to vary a cutting length of the cutting unit within a cutting length range, the actuator (16) being moveable between a first actuator position corresponding to a first extreme cutting length of the cutting length range, and a second actuator position corresponding to a second extreme cutting length of the cutting length range; a user-moveable control element moveable between a plurality of control positions including: a range of length control positions between a first control position corresponding to the first actuator position and a second control position corresponding to the second actuator position; and an off position corresponding to deactivation of the drive, wherein the off position is adjacent the first control position. In use the actuator is in the first actuator position when the drive is deactivated by movement of the control element to the off position.
