Abstract
A keyboard includes a base plate, a membrane circuit board, a backlight module, and a plurality of keyswitch assemblies. The base plate has a plurality of through holes. The membrane circuit board is disposed on the base plate. The backlight module is disposed at a side of the base plate away from the membrane circuit board and configured to emit light toward the base plate. The keyswitch assemblies are disposed on the membrane circuit board. Each of the keyswitch assemblies includes a position-returning member located over one of the through holes. An orthogonal projection of the position-returning member projected on the base plate overlaps a part of said one of the through holes.
