Abstract

A sensing keyswitch including a key body, a key-sensing switch and an enabling switch is provided. The key body includes a key top, and a key driver and an enabler which can move with the key top in the same keystroke cycle. The key-sensing switch electrically connected to a key circuit is in a disabled mode to save power and cannot sense the change of the sensing intensity caused by the movement of the driver. The enabling switch is electrically connected to an enabling circuit, wherein when the enabling switch is triggered by the enabler, the enabling switch outputs an enabling signal through the enabling circuit for enabling the key-sensing switch to enter an enabled mode, so that the key-sensing switch can sense the change of the sensing intensity caused by the movement of the key driver to trigger a key signal.
