BUTTON ASSEMBLY WITH DRIVE ASSEMBLY

摘要

A process is provided for characterizing a tactile response of a first mechanical actuator (e.g., button) based on a back off distance. The first mechanical actuator may include a plunger, a dome-shaped flexible membrane, and an electrical contact, all aligned with each other so that a contact signal is generated when the flexible membrane touches the contact. The plunger can be moved a first distance towards the contact until the contact signal is generated at a contact point. Then the plunger can be backed off a second distance from the contact point. This second distance may be called the“back off distance”. The particular feel of the first mechanical actuator can then be correlated to a particular back off distance. This process can be repeated a number of times to classify a number of different“feels”for the first mechanical actuator based on a number of different back off distances.
