The invention relates to a rotary switch (10, 110, 210, 310) for controlling an electronic parking brake device (12, 112, 212, 312) of a commercial vehicle, having a knob (14, 114, 214, 314) and the knob counterpart (16, 16, 216, 316), the knob (14, 114, 214, 314) and the knob counterpart (16, 116, 216, 316) are rotatably connected to each other and can rotate about a common axes (D, 1D, 2D, 3D) are twisted relative to each other, the knobs (14, 114, 214, 314) are additionally able to rotate relative to the counterpart ( 16, 116, 216, 316) to move axially, the rotary switch (10, 10, 210, 310) has at least one manipulation switch state (S2P, 1S2P, 2S2P, 3S2P) and at least one release switch state (S2D, 1S2D, 2S2D, 3S2D), manipulating the switch state (S2P, 1S2P, 2S2P, 3S2P) by the knob (14, 114, 214, 314) in the first rotation direction (DR1, 1DR1, 2DR1, 3DR1) and / or The movement of the knob (14, 1, 14, 214, 314) along the first axis of the first movement direction (VR1, 1, VR1, 2VR1, 3VR1) causes the release of the switch state (S2D, 1S2D, 2S2D, 3S2D) A second rotational movement by the knob (14, 14, 214, 314) in the second direction of rotation (DR2, 1DR2, 2DR2, 3DR2) and / or a second rotational movement of the knob (14, 14, 214, 314) in the first direction of movement (VR1 , 1VR1, 2VR1, 3VR1) caused by the second axial movement.
