PROBLEM TO BE SOLVED: To provide a push-button-switch-attached rotational electronic component which has a reduced part number, is easily assembled, can be reduced in thickness, does not have play upon on/off operations of a push button switch, and has an anti-electrostatic measure. SOLUTION: A structure is disclosed, in which a rotating knob 61 is pushed down of its radius direction so that a rotational electronic part is descended with respect to an attaching stand 10 and thus switch contacts formed on a switch substrate 10 are on/off. Engaging sections 15, 53 are provided in such a manner that a base 51 can be moved with respect to the attaching stand in the vertical directions. The engaging section 53 has a support 53a and a head 53b having a width larger than the support 53a. The engaging portion 15 has an inserting section into which the head 53b is inserted; and a guide section 15b for holding the support 53a. The head 53b is inserted into the inserting section 15a and slid in the vertical directions to insert the support 53a into the guide section 15b.
