A digitizing stylus which generates a pulse that is not dependent upon the spatial displacement of the contacting pin, embodied in accordance with the invention so that the toroid coil can be moved axially, together with the contacting pin. This preferably is attained by providing that the contacting pin and the toroid coil are integrally cast in plastic, and the plastic body thereby formed has an extension on its inner end which extends to interconnect with an actuation body that is held within the shaft of the digitizing stylus, in an axially movable manner. Excitation of the toroid coil is triggered by the displacement of the actuation member, and a constant amplitude pulse will occur because no movement occurs between the contact pin and the toroid coil.
