Abstract
An illuminated switch includes a lens that is provided integrally with a converter on a surface opposing a light-emitting element disposed on a base constituting a switch body. The lens diffuses light emitted from the light-emitting element through the inner space of a coil spring urging a switch operating unit in the vertical direction. Moreover, a tilted surface is formed at an angle inclining towards the bottom surface of a hole below from the upper surface of the switch operating unit in the axial direction.
