Abstract
A keyboard includes a non-conductive board, a plurality of keyswitches, and a capacitive touch sensing sheet. The plurality of keyswitches is disposed on the non-conductive board. Each keyswitch includes a keycap and a support device. The support device is connected to the keycap and the non-conductive board so as to make the keycap movable between a pressing position and a non-pressing position relative to the non-conductive board. The capacitive touch sensing sheet is disposed under the non-conductive board for providing a cursor signal to a computer device.
