Abstract
A multi-functional key module, configured to be installed in an electrical appliance, includes a hollow main housing, a pin, an electronic key, and an optical tracking chip, a contact trigger end of the electronic key is arranged towards the pin, and the electronic key gives an electrical signal when triggered by contact. The optical tracking chip emits a detection laser to the side surface of the pin and receives reflected light, and determines a motion state of the pin to generate an electrical signal; and the electronic key and the optical tracking chip are electrically connected. In the application, corresponding electrical signals are generated by pressing the key cap to trigger the electronic key, rotating the key cap, or pressing the key cap without causing the pin to trigger the electronic key, so that the composite control effect of a single key is achieved.
