PROBLEM TO BE SOLVED: To provide a multiple rotation switch capable of simply increasing rotation switches without changing a shaft or an entire multiple rotation switch when there is a need for changing the number of rotation switches due to addition, change or the like of electric circuits.SOLUTION: The multiple rotation switch includes a rotation switch 12 having: a casing 14 in which a through hole 15 for inserting a shaft is formed; a rotation body 18 which is rotatably provided in the casing 14; and a switch 23 which is also provided in the casing 14 and is turned on and off together with a rotation action of the rotation body 18. A predetermined number of rotation switches 12 are overlaid on and fixed to each other while the through holes 15 are aligned with each other. The shafts are inserted in the through holes 15, and the rotation bodies 18 of the respective rotation switches 12 are operated to rotate at the same time by rotation of the shafts. The shaft is constituted by a plurality of short pieces 16 which are divided so that they can be jointed to each other, and the short pieces 16 of the shafts are constituted so that they can transmit a rotation force to each other while they are jointed.
