Abstract: A keyswitch assembly includes a switch module, a support mechanism, and a blocking mechanism. The switch module includes a substrate, a signal generator, and a signal sensor. The signal generator provides a sensing signal. The signal sensor receives the sensing signal to obtain a sensing intensity. The support mechanism is disposed on the substrate. A top portion of the support mechanism moves in response to a pressing force. The blocking mechanism includes a pivoting portion rotatably disposed on the substrate, a connecting piece extending from the pivoting portion and movably connected to the support mechanism to be driven by the top portion to swivel relative to the substrate, and a blocking piece extending from the pivoting portion and driven by the connecting piece to be inserted into or escape from the gap between the signal generator and the signal sensor to change the magnitude of the sensing intensity.

Abstract: A keyswitch assembly includes a switch module, a support mechanism, a blocking mechanism, an enhancing light source, and a backlight source. The switch module includes a substrate, a signal generator, and a signal sensor. The signal generator generates a sensing signal. The signal sensor receives the sensing signal to obtain a sensing strength. The support mechanism is disposed on the substrate. The blocking mechanism is disposed on the substrate and has a light-permeable portion. A portion of the blocking mechanism inserts into or escapes from a gap between the signal generator and the signal sensor. The backlight source is disposed on the substrate and located outside the vertical projection of the blocking mechanism on the substrate. The enhancing light source is disposed on the substrate and located within the vertical projection of the blocking mechanism on the substrate and corresponds to the light-permeable portion.
