Abstract: A main body of an illuminating knob is formed as a base made of a transparent resin. An undercoat layer and a topcoat layer are applied on a peripheral surface of the base. A pattern inside eliminating portion is formed in a shape of an indicating pattern as a marked portion by a laser etching or a partial exfoliation of the topcoat layer on the bottom portion. By passing light from a light source provided inside of the knob through the marked portion, an indication via passing through light is achieved.

Abstract: A rocking member is swingably supported on one opening side of a cylindrical case, and a knob is attached to the rocking member. The rocking member is provided with a rocking arm extending therefrom in the longitudinal direction of the case. The rocking arm has a tip section for engaging projections of a contact holder. The contact holder is moved in a direction perpendicular to the longitudinal direction of the case by the swinging action of the rocking arm, thereby switching a plurality of circuits. As a result, the switch can be made compact and its structure can be simplified.
