1. A keyswitch assembly, comprising:
a switch module comprising a substrate, a signal generator, and a signal sensor, wherein the signal generator and the signal sensor are disposed on the substrate, the signal generator is configured to provide a sensing signal to the signal sensor, and the signal sensor is configured to receive the sensing signal to correspondingly obtain a sensing intensity;
a support mechanism disposed on a top surface of the substrate, a top portion of the support mechanism moving along an up-down direction in response to a pressing force; and
a blocking mechanism comprising:
a pivoting portion rotatably disposed on the top surface;
a connecting piece extending from the pivoting portion, the connecting piece movably connected to the support mechanism to be driven by movement of the top portion, so as to swivel along the up-down direction relative to the substrate; and
a blocking piece extending from the pivoting portion, the blocking piece configured to be driven by the connecting piece to be inserted into or escape from a gap between the signal generator and the signal sensor, so as to change a magnitude of the sensing intensity.
