Abstract
An input device including a housing and a depressible key plate disposed thereon. The key plate includes a front user-accessible portion, a pivot support portion, and a rear portion. A shaft is disposed in the pivot support portion, where the key plate rotates with respect to the shaft. A force sensor is disposed in the housing and in contact with a bottom surface of the front portion of the key plate, and activates in response to receiving a predetermined force by the bottom surface of the front portion of the key plate. The depressible key plate depresses in response to receiving a predetermined depression force on the top surface. A biasing mechanism is disposed in the housing and in contact with the bottom surface of the rear portion of the key plate to provide an upward force tuned to be substantially equal to the predetermined depression force.
