To provide a slide switch structure with a slide knob not easily moved under normal conditions.

This slide switch structure is made up of a slide switch 3 mounted on a substrate 2 housed in an enclosure 1, and a slide knob 4 for operating the slide switch. The slide knob comprises a knob operating part 41 projectingly provided so as to project from a slide hole 11 bored in the enclosure 1 to the exterior of the enclosure, fit holes 42, 42,... to be fitted to lock projections 12 projectingly provided so as to project from the enclosure 1 into the interior thereof, and elastic parts 5 for holding/releasing the fitting of the lock projections 12 to the fit holes 42 by elastic repulsing from the side of the substrate 2 toward the enclosure direction. The elastic parts are made up by cutting cutouts 44, 45 in a leg part 43 of the slide knob erected toward the substrate direction.
