ABSTRACT:
An electronic pen has a force sensor whose electrical resistance varies in accordance with the amount of force applied to the pen stem of the pen. The force sensor is a modular unit with an electrode and a closure, which are mutually arranged in an essentially electrically insulated initial position. The closure, which conveniently is cantilevered on the electrode, is adapted to receive axial forces from the pen stem and thereby to be urged to an activated position in electrical contact with the electrode. The closure is also arranged, on relaxation of the axial forces, to automatically spring from the activated position back to the initial position.
