Abstract: A combined dual-conductive key switch including a base, a cover arranged above the base and a conductive core, wherein the combined dual-conductive key switch further includes a mechanical-conducting component and a light-conducting component which are electrically connected to a PCB respectively, wherein a conduction trigger block corresponding to the mechanical-conducting component and a light-blocking protrusion corresponding to the mechanical-conducting component are respectively arranged on the conductive core; and the conduction trigger block triggers a conduction stroke of conducting the mechanical-conducting component, which is different from the conduction stroke of conducting the light-conducting component triggered by the light-blocking protrusion. The combined dual-conductive key switch is provided for achieving dual-conductive functions of pressing once and performing two actions for a product.
