Abstract
Example embodiments relate to stylus. For example, a stylus includes a pressure sensor and a sensor holder in contact with the pressure sensor. The stylus also includes a first spring having a distal end and a proximal end. The distal end is in contact with the sensor holder. The stylus further includes a spring holder in contact with the proximal end. The stylus further includes a second spring in contact with the sensor holder to apply a preloading force to the pressure sensor. The entirety of the spring holder and a portion of the first spring are positioned within the second spring. The stylus further includes a tip portion in contact with the spring holder to compress the first spring in response to a compressing force applied to the tip portion.
