Abstract
A force sensor may include a sensing die with a sense diaphragm. An actuation assembly may include a button member and a pin and/or other features, where a first end of the pin may engage the sense diaphragm and a second end of the pin may engage the button to facilitate transferring a force applied to the button to the sense diaphragm. In some cases, the interface between the button member and the pin may allow the button member to swivel or pivot, at least to some degree, relative to the pin, which may facilitate transferring a force from the button member to the diaphragm with minimal mechanical loss. In some cases, the second end of the pin may be at least partially tapered, with the taper engaging the edge of an indentation in the button.
