1. A detection device for detecting a position of a moving object, wherein the detection device comprises:
a base;
an arm that is mounted rotatable to the base, wherein the arm is rotatable around a first rotational axis and has a free end for contact with the moving object; and
a sensor that is configured to detect rotation of the arm relative to the base, wherein the sensor has a first part and a second part, wherein the first part moves with the arm, and the second part is attached to the base;
the first part being a first component of a magnet switch pair,
the switch being an electrical switch that is configured to be actuated by the magnetic field of the magnet,
the second part being a second component of the magnet switch pair,
the electrical switch being in an initial state when the arm is in a first rotational position, and wherein the electrical switch is in a second state when the arm is in a second rotational position that is different from the first rotational position, and that
the detection device comprising a reset device that is a spring, which is configured to move the arm from the second rotational position into the first rotational position,
the arm comprising a first section on the free end of the arm that is mounted rotatable to the base, and a second section that extends from the first section,
the second section being mounted rotatable to the first section,
the second section being rotatable around a second rotational axis that is orthogonal to the first rotational axis.
