Illuminated push-button electrical switch assembly
Abstract
Abstract An illuminated push-button switch assembly has a casing slidably mounting a manipulation member provided at its exterior end with an indicating plate. A light source is mounted in the casing to illuminate the indicating plate. The switch assembly further has shutter means constituted by a filter member and a drive member. The filter member is rotatably supported at its one end on the casing, while the filter member is rotatably supported at its intermediate portion by the manipulation member. The free end of the drive member is engageable with the filter member at the portion of the latter near the axis of rotation. As the slider is moved by manual operation of the manipulation member, the drive member is rotated to cause a rotation of the filter, so that the state of illumination of the indicating plate is changed in accordance with the state of the push-button switch. A large displacement of the driving member and, hence, a large rotation angle of the filter member, is obtained even by a small stroke of the slider, thanks to a suitable selection of positions of the operating and supporting points.
