An electronic pen comprises a retractable cartridge, a retraction mechanism for extending and retracting the cartridge, a button for actuating the retraction mechanism, a sensing arrangement for sensing a configuration of the pen, and a processor cooperating with the sensing arrangement. The processor is adapted to configure a state of the pen in response to input signals from the sensing arrangement. The sensing arrangement comprises a button sensor coupled to the button, which senses actuation of the button and a cartridge sensor for sensing whether the cartridge is extended or retracted.
