Abstract
An illuminating push-button device includes a key-top part having a key-top surface and a first protrusion that protrudes from a back side of the key-top surface. The device also includes a key rubber part made of a transparent or semi-transparent elastic material and having a second protrusion that receives the first protrusion, the second protrusion being oriented in a common direction as the first protrusion. A switching device is included that opposes the second protrusion and is configured to be actuated in response to the key-top part being depressed. A light-source element emits light from a light-emitting surface and cooperates with a light-blocking sheet disposed between the light-source element and key rubber part and covers at least a portion of the light-emitting surface of the light-source element and has a loose hole through which the second protrusion of the key rubber part is passed.
