PROBLEM TO BE SOLVED: To provide an inexpensive multiple button type switch device of irradiation type with excellent assemblability and stable quality. SOLUTION: First and second buttons 2 and 3 are integrally molded with a button frame 12, and a third button 6 is integrated with a button cover 7 through the button frame 12, so that a button group unit 13 is previously formed with the button frame 12, the third button 6 and the button cover 7 and built in an opening 1a of a nose member 1. A transparent hole 9b is formed in each swelled part 9a of a rubber contact 9, and the light of an LED 10 is guided from the transparent hole 9b of the swelled part 9a through the inside of actuator parts 5d, 5e and 7d to irradiation parts 2a, 3a and 6a, so that the respective buttons 2, 3 and 6 can be molded with a simple die without molding them with double colors. Additionally, a shading wall 8b overlapping with a flange part 7a of the button cover 7 is formed on a button holder 8, so that the light of the respective LEDs 10 is prevented from intruding into the inside of the adjoining actuator parts 5d, 5e and 7d by the shading wall 8b.
