In the driving position the ignition lock allows operation of an engine of the motor vehicle. In the stationary position operation of the engine is blocked. An indicating device is controlled by a switch operable by the locking cylinder at the point of directional change. ## Claims ### Claim at position 1 1-14. (canceled) ### Claim 15 An ignition lock for a motor vehicle comprising: a locking cylinder configured to receive a suitable key and shiftable along a path between a driving position in which the ignition lock enables operation of an engine of the motor vehicle, and a stationary position in which the ignition lock diables operation of the engine, wherein the path includes a point of directional change; a switch operable by the locking cyliner at the point of directional change; and a display activated by the switch to display information pertaining to movement of the locking cylinder along the path. ### Claim 16 (depends on 16) The ignition lock according to claim 16, wherein the display comprises a monitor. ### Claim 17 (depends on 16) The ignition lock according to claim 16, wherein the display comprises a multi-function display instrument. ### Claim 18 (depends on 16) The ignition lock according to claim 16, wherein the path of the locking cylinder from the driving position into the stationary position comprises at least a first rotation about an axis to the point of directional change and a translation along the axis of first rotation. ### Claim 19 (depends on 18) The ignition lock according to claim 18, further comprising a spring biasing the locking cylinder against translation along the axis of rotation. ### Claim 20 (depends on 18) The ignition lock according to claim 18, wherein the path comprises a second rotation following the translation. ### Claim 21 (depends on 20) The ignition lock according to claim 20, wherein the second rotation is about the axis of rotation. ### Claim 22 (depends on 16) The ignition lock according to claim 16, further comprising: a contact field arranged on a surface adjacent the locking cylinder; and a contact complementary to the contact field coupled to the locking cylinder and movable on the surface between a first position contacting the contact field and a second position disconnected from the contact field. ### Claim 23 (depends on 15) The ignition lock according to claim 15, wherein the switch is operable by a torque acting on the locking cylinder at the point of directional change. ### Claim 24 (depends on 15) The ignition lock according to claim 15, further comprising a control unit configured to activate the display, when the switch is continuously operated during a predefined time interval. ### Claim 25 (depends on 15) The ignition lock according to claim 15, further comprising a control unit configured to activate the display when the switch is repeatedly operated during a predefined time interval. ### Claim 26 (depends on 15) The ignition lock according to claim 15, further comprising first and second stages extending along the axis, wherein the first stage is movable by the locking cylinder to contact the second stage at the point of directional change. ### Claim 27 (depends on 26) The ignition lock according to claim 26, wherein at least a portion of the switch is provided on the second stage. ### Claim 28 (depends on 26) The ignition lock according to claim 26, wherein the second stage comprises a transfer body extending annularly around the locking cylinder. ### Claim 29 (depends on 28) The ignition lock according to claim 28, wherein the switch is arranged between the transfer body and a vehicle-fixed holder.
