1. An electronic device comprising:
an enclosure comprising a sidewall, the sidewall defining an opening; and
a haptic button assembly comprising:
an input member positioned at least partially in the opening and defining an input surface;
a contact member positioned at least partially within the enclosure and coupled to the input member, the contact member configured to receive a first force in response to a force input applied to the input surface;
a strain sensing element coupled to the contact member and configured to detect a strain resulting from the force input; and
a haptic actuation system configured to, in accordance with a determination that the strain satisfies a condition, impart a second force on the contact member, thereby causing the input member to move to produce a haptic output.
