Abstract
A joystick includes a stick and a base attached to the stick. The joystick includes a housing in which part of the base is disposed. The housing includes a baseplate. A predetermined number of magnets correspond to the number of pivot-axes. The magnets are attached to the base, and each of the magnets defines a pivot-axis around which the base can be. The pivot-axis is defined by one of the magnets diametrically opposite to this magnet. A magnetic element, in particular a plate, is attached to or is part of the baseplate. The joystick further includes a sensor for detecting rotation of the base around at least one of the predetermined number of pivot-axes. The base and the magnets attached to the base are disposed facing the magnetic element and interacting with the magnetic element such that an attractive force is pulling the magnets toward the magnetic element.
