Abstract
There is provided an illuminated switch construction, which make it possible to ensure excellent visibility and operability of the illuminated switch, while the illuminated switch can be compact in size, cost-reduced and simple in structure. A substrate is formed therein with a plurality of guide holes. A switch unit and an LED are arranged on the substrate at locations adjacent to each other. The switch unit has a driven part driven for reciprocating motion. A pushbutton unit is formed by a diffuser sheet and a button body which are stacked one upon the other on a lamp house. A plurality of guide pins extend from the lamp house and are fitted through the respective guide holes. The lamp house has a fitting part formed therein with a fitting hole in which a head part of the driven part of the switch unit is fitted and held. When a depressing part of the button body is depressed, the pushbutton unit performs reciprocating motion in a manner interlocked with the driven part. The guide pins slide within the respective guide holes, whereby the reciprocating motion of the pushbutton unit is guided.
