Regulator assembly for an aircrew breathing mask

A control unit for an aircraft crew member's breathing mask, includes a support, a mode-selection knob pivotally mounted on a holder between at least a first position, a second position and a third position. A controller supplies a breathing cavity in three modes of operation depending on the position of the mode-selection knob. A locking/unlocking system includes an operating member moveable between a locking position and an unlocking position. The locking position blocks the rotation of the mode-selection knob from the second position to the third position, and the unlocking position allows rotation of the mode-selection knob from the second position to the third position.
