Abstract
A button structure of an input device, including a circuit board, a dome element, and a trigger, is provided. The dome element is disposed on the circuit board, and is electrically conductive and elastic. The trigger is disposed at a center of the dome element, and is electrically insulative and flexible. The trigger has a conductive layer facing the circuit board. The dome element is configured to be pressed to drive the conductive layer of the trigger to abut against a trigger circuit of the circuit board to generate a trigger signal.
