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.
