PROBLEM TO BE SOLVED: To provide a switch structure for restoring a disk in a short time. SOLUTION: In the switch structure, a substrate 21 provided with a pattern circuit where first fixed contact points 32a-32e and a second fixed contact point 33 are formed on a surface, dome-like disks 23-27 mounted on the first fixed contact points 32a-32e and the second fixed contact point 33 and a flexible cover 30 bonded while covering the substrate 21 and the disks 23-27 are arranged on the recessed part 13 of the hand operation body of this vacuum cleaner, and the first fixed contact points 32a-32e and the second fixed contact point 33 are electrically connected by the recess of the disks 23-27 caused when the disks 23-27 are pressed from the above. Ventilation holes 36a-36e for releasing air inside a dome formed by the disks 23-27 to the outside when the disks 23-27 are recessed and for introducing outside air into the dome when the disks are restored to an original shape are formed at the cover 30 from positions near the disks 23-27 to the positions to be overlapped with the disks 23-27.
