Note 1) For each cylinder series, when a compact auto switch is mounted on the three sides (A, B and C above)
        other than the port side of bore sizes ø32 to ø50, the auto switch mounting brackets above are required.
        Order them separately from cylinders.
        (It is the same as when mounting compact cylinders with an auto switch mounting rail, but not with ø63
        compact auto switch installation groove.)
