To provide an aggregate entrance machine to which many kinds of key switches for autodoor opening and shutting can be attached.

A key-switch case 4, which is used to fix a key switch 2 to the aggregate entrance machine panel 3 of this aggregate entrance machine 2, is provided. The key-switch case is provided with a substantially cylindrical key-switch fitting and mounting cave 41 to and on which the key switch is fitted and mounted. A part on the outer circumference of the key-switch fitting and mounting cave is formed as a cylindrical part 42. A key-switch fixation hole 5, to which the cylindrical part is fitted, is bored and formed in the aggregate entrance machine panel. Key-switch cases in the required number of key switches are prepared. Since the size of the cylindrical part of every key-switch case is made constant the key-switch fixation hole in the corresponding aggregate entrance machine panel can be reduced to one kind. Consequently, many kinds of key switches for autodoor opening and shutting can be attached to the aggregate entrance machine of one kind.
