1. A clickable trackpad comprising:
a printed circuit board assembly (PCBA) and attached touch sensor;
a switch to register a user depression of the touch sensor;
a pair of flexure mechanisms, each flexure mechanism including:
a pair of bonding pads, each of the bonding pads fixed to an underside of the PCBA;
a pair of rotatable linkages, each of the rotatable linkages to rotate in response to compression of an associated one of the flexure mechanisms;
a transmission bar to rotationally link the rotatable linkages; and
flexures connecting the bonding pads, rotatable linkages, and the transmission bar; and
one or more torsion bars to rotationally link the flexure mechanisms, wherein a combination of the flexure mechanisms and the switch defines an activation threshold force for the touch sensor and a release threshold force for the touch sensor.
