Abstract:
1. An illuminated push button unit comprising: a light-guide lens configured to guide light from a light source to a light emission face disposed at a front end of the light-guide lens and emit the light from the light emission face; a lens holder configured to be pivotally attached to a front panel of an electrical device to support the light-guide lens relative to the front panel so that the light-guide lens pivots about a fulcrum portion of the lens holder relative to the front panel, the lens holder including a light emission window through which the light emission face of the light-guide lens emits the light; a push-down control attached to the light emission face in a middle of the light emission face so that the light emission face emits the light in an annular shape, the push-down control having a tapered peripheral surface that tapers toward a distal end portion of the push-down control; and a cylindrical translucent body configured to be fixedly coupled to an opening of the front panel, the cylindrical translucent body being disposed on a front side of the front panel relative to the light emission face of the light-guide lens, the tapered peripheral surface of the push-down control being fitted within a through hole of the cylindrical translucent body and movable along the through hole of the cylindrical translucent body relative to the through hole of the cylindrical translucent body together with the light-guide lens when the light-guide lens pivots relative to the front panel.
