Abstract

The invention provides an input device, including: a substrate, including at least one connecting portion and at least one limiting portion; at least one key, including at least one first engagement portion and at least one second engagement portion located on two opposite sides, where the first engagement portion is in contact with the connecting portion, so that the key can rotate relative to the substrate by taking the connecting portion as a rotation center, and the second engagement portion faces the limiting portion and is spaced apart from the limiting portion; and a buffer unit, disposed on at least one of two surfaces of the limiting portion and the second engagement portion facing each other. By disposing the buffer unit, noise generated due to the collision between the second engagement portion and the limiting portion can be decreased.
