Abstract
A position detection assembly for detecting a spatial position of a moveable element. The assembly includes a colour sensor and one or more colour indicators provided on a surface of the moveable element. The colour sensor is spaced from the surface of the moveable element and arranged to emit light onto the surface and detect light reflected from the surface and to determine the position of the element based on the reflected light.
