PURPOSE:To utilize a panel face effectively, select a function directly, and relieve restriction on the orders of wirings and the functions substantially. CONSTITUTION:A support piece for supporting a button main body 25 is provided flexibly on a rotary body, and the rotary body is hold between a panel 33 and a panel base 35 so as to rotate freely. In the case of function selection, after the rotation position of the button main body 25 is set, the button main body 25 is pushed in so as to warp the support piece, and the drive portion 39 of a tact switch 40 is pressed by a boss 32 provide on the bottom face side of the support piece, so that the tact switch 40 is turned on. Thereby, although an operation switch is a rotary type, it is possible to switch the functions directly, make the occupying space of a operation button small on a panel face, and further relieve the restriction on the order of the wirings of the contact switches 40 and the functions substantially. |
