Claims

[Scope of utility model registration request]

An illuminated switch comprising a key top made of a light-transmitting material, and a light emitting element that irradiates light from the outside onto the peripheral surface of the key top and illuminates the operation surface of the key top with the light scattered inside the key top. In the above, the key top is
An illuminated switch characterized in that a reflective layer for reflecting light passing through the interior of the key top is provided on a surface of the peripheral surface that faces an incident surface on which light emitted from the light emitting element enters.
