PROBLEM TO BE SOLVED: To provide a ventilating fan switch which improves operatability, and which can be mounted on a mounting frame together with other wiring instruments. SOLUTION: A body 1 of a ventilating fan switch A corresponds to an elongated mounting frame C having a longitudinal opening window including a three sets of instrument mounting sections, and the external configuration size of the body 1 corresponding to a short width direction of the opening window is formed into substantially the same size as the size of the short width direction of the opening window. Further, an external configuration size of the body 1 corresponding to a longitudinal direction of the opening window is formed into substantially 2/3 times the longitudinal size of the opening window. There are disposed on a front surface of the body 1 an operation handle 20 of a push button switch for switching a ventilating fan on/off, and a slide operation knob section 31 of an operation change-over switch for selectively changing over an operation holding time of the ventilating fan from a plurality of previously set times. |
