PURPOSE:To provide an illumination type switching apparatus of which a through hole of a switch part is made to be a small shape to prevent invasion of dust and water drops and the whole of the switch operation part can be illuminated. CONSTITUTION:A transparent or semitransparent cover part 17 is unitedly fused on an open part 16a formed in a case main body 16 and at the same time a through hole 17a is formed in the cover part 17. An operational part 13A is put on the upper side of the cover part 17 and a shaft 15 which is press- inserted into the lower face of the operational part 13A is penetrated into the through hole 17A in the way it can slide freely, so that a switch in a wrist watch case can be opened or closed. An illuminating element 25 is installed on the opposite to the cover part 17 in the wrist watch case 10 and light is radiated to the operational part 13A through the cover part 17. |
