Abstract
An electronic stylus device includes one or more mechanisms that deform to protected an electronic force sensor. After the mechanism deforms to relieve force applied to a tip of the stylus, a hard stop may engage to arrest further movement of a shaft transferring force from the tip to the force sensor. The intermediate range of forces that may be relieved by the mechanism, in addition to providing the electronic force sensor, enables less stringent manufacturing tolerances to be used with the hard stop.
