Contact actuator for a vehicle

The actuator has a cylindrical barrel (202) that is intended to swivel around an axis (A1). A handle (106) includes a rod (108) extending according to the axis. The rod is arranged interdependent of the barrel in rotation around the axis. A feeler (210) is mounted on the barrel. The feeler moves a pull knob (114) from its unlocking position towards its locking position in one position. The feeler inhibits the knob from moving from its unlocking position towards its locking position in another position when the rod slides between its advanced position and its moved back position.
