Abstract

A keyboard with light-emitting and touch functions includes a keyswitch, a backlight module having a light source and a light guide plate, a membrane, a capacitive touch sensing sheet disposed on the membrane and the light guide plate, and a board. The keyswitch includes a cap and a support mechanism movably connected to the cap. Light of the light source is incident into the light guide plate and is emitted toward the cap. The membrane has a switch and is selectively disposed on or under the backlight module. The board is disposed under the backlight module and the membrane and has first and second connection members. The first and second connection members pass through the membrane, the light guide plate and the capacitive touch sensing sheet to be movably connected to the support mechanism, so as to make the cap movable downward relative to the board for triggering the switch.
