`
`a holder configured to hold the push button, the push button being
`
`10 movable in a longitudinal direction of each indicator lens;
`
`a detector configured to detect a displacement of the push button in the

`as seen in a section perpendicular to the longitudinal direction and a
`
`25
`
`juxtaposition direction of each indicator lens, and

`the one of two dent being facing one of adjoining indicator lenses out of
`
`the plurality of indicator lenses and the another of two dent being not facing
`
`other of the plurality of indicator lenses.
`
`20
`
`6. The illumination switch device according to claim 5, wherein
`
