Abstract
In one aspect of the present invention, a contactless inductance switch is disclosed for use with a joystick. The switch is mechanically connected to a mass which is movable between a first and second position. When an operator presses the switch, the mass moves to the second position adjacent to an electrical circuitry. Sensing circuitry measures the change in inductance in the coil and produces a control signal indicating that the switch was pressed.
