Keyboard providing power control

摘要

A keyboard includes a plug communicating with an external input device, a printed circuit board (PCB), and a base. The PCB includes a first power pad and a second power pad electrically connected to the plug via a cable. The PCB outputs a control signal to the plug via the cable in response to the first power pad and the second power pad being electrically connected. The base includes a control and at least one positioning element for positioning the control on the base. The control includes a pushbutton, a first pin electrically connected to the first power pad, and a second pin electrically connected to the second power pad. The first pin and the second pin are electrically connected in response to the pushbutton being pressed.
