Contact actuator for a motor vehicle, comprising: - a barrel intended to pivot about an axis A1, - a handle comprising: - a rod extending along the axis A1, inserted into the barrel by a first end and intended to slide in the latter between an advanced position and a retreated position, the rod being coupled in rotation to the barrel about the axis A1, and - a head fixed to a second end of the rod and by which the handle is intended to be seized and manipulated, and - a pull bar intended to move between a position for locking a steering column and a position for unlocking the steering column, the contact actuator being characterized in that the rod has: - a groove inclined with respect to the axis A1 and formed in the rod, and in that it additionally comprises: - a feeler mounted on the barrel and pivoting about an axis A3, the feeler having a pin inserted into the inclined groove in such a way as to pivot the feeler between a first position in which the feeler allows the pull bar to move from its unlocking position to its locking position and a second position in which the feeler prevents the pull bar from moving from its unlocking position to its locking position when the rod slides between its advanced position and its retreated position. - a barrel intended to pivot about an axis A1, - a handle comprising: - a rod extending along the axis A1, inserted into the barrel by a first end and intended to slide in the latter between an advanced position and a retreated position, the rod being coupled in rotation to the barrel about the axis A1, and - a head fixed to a second end of the rod and by which the handle is intended to be seized and manipulated, and - a rod extending along the axis A1, inserted into the barrel by a first end and intended to slide in the latter between an advanced position and a retreated position, the rod being coupled in rotation to the barrel about the axis A1, and - a head fixed to a second end of the rod and by which the handle is intended to be seized and manipulated, and - a pull bar intended to move between a position for locking a steering column and a position for unlocking the steering column, - a groove inclined with respect to the axis A1 and formed in the rod, and in that it additionally comprises: - a feeler mounted on the barrel and pivoting about an axis A3, the feeler having a pin inserted into the inclined groove in such a way as to pivot the feeler between a first position in which the feeler allows the pull bar to move from its unlocking position to its locking position and a second position in which the feeler prevents the pull bar from moving from its unlocking position to its locking position when the rod slides between its advanced position and its retreated position. - a feeler mounted on the barrel and pivoting about an axis A3, the feeler having a pin inserted into the inclined groove in such a way as to pivot the feeler between a first position in which the feeler allows the pull bar to move from its unlocking position to its locking position and a second position in which the feeler prevents the pull bar from moving from its unlocking position to its locking position when the rod slides between its advanced position and its retreated position.
