Abstract: A key module includes a bracket, a circuit film assembly, a keycap, and a connecting structure. The bracket includes a bottom plate and a bracket pivotal portion protruding from the bottom plate. The circuit film assembly is disposed on the bracket and includes a plurality of film layers and a supporting portion formed by at least one of the film layers. The supporting portion is located beside the bracket pivotal portion. The keycap is disposed above the bracket and the circuit film assembly and includes a keycap pivotal portion. The connecting structure is disposed between the bracket and the keycap and includes a first pivot pivotally disposed at the bracket pivotal portion and a second pivot pivotally disposed at the keycap pivotal portion. The supporting portion beside the bracket pivotal portion supports the first pivot, such that the first pivot continuously contacts the bracket pivotal portion.
