The rectangular projection 9 formed in one direction is integrally formed. The two projections 9 are designed and sized so that they fit into a rectangular notch 10 formed in the inner edge of the opening 2 of the support plate 1 along the longitudinal direction.

The switch operating plate 6 is provided with a U-shaped claw portion 6 a that engages with the switch lever 5 a of the slide switch 5 mounted on the substrate 11, and the erroneous operation preventing plate 4 is provided on the back surface of the supporting plate 1 at the center thereof. A protrusion 13 for positioning the coil spring 12 for pressing is formed. Two legs 14 arranged along the longitudinal direction of the opening 2 of the support plate 1 are formed on the lower surface of the slide knob 3, and the lower ends of the legs 14 slightly project to the opposite sides. A locking portion 14a that forms a portion is provided.

When the slide knob 3 is placed on the support plate 1, the leg portion 14 is inserted into the device through the opening 2 and passes through the leg portion passage hole 15 formed in the erroneous operation preventing plate 4 and It fits into the engaging hole 16 of the switch operating plate 6 located below, and the engaging portion 14a at the lower end of the leg portion 14 elastically engages using the edge portion of the hole 16. As a result, the slide knob 3 is connected to the erroneous operation prevention plate 4 and the switch operation plate 6, and the movement of the slide knob 3 is transmitted to the switch operation plate 6 so that the switch lever 5a is operated by the U-shaped claw portion 6a. The distance between the legs 14 integrally formed on the lower surface of the slide knob 3 is shorter than the length of the opening 2 formed in the support plate 1 in the longitudinal direction. It becomes possible to slide in the longitudinal direction within the range where it abuts the section.

The erroneous operation prevention plate 4 is constantly pressed against the back surface of the support plate 1 by the coil spring 12. Therefore, when the claw portion 6a of the switch operation plate 6 is in the position for holding the switch lever 5a in its neutral position, the operation prevention plate 4 is in the longitudinal intermediate position in the opening 2 of the support plate 1 and has two protrusions. The portion 9 is fitted in the cutout portion 10. As a result, in this state, the movement of the slide knob 3 is restricted by the operation prevention plate 4.

When the switch operation plate 6 in the neutral position is moved in either direction, the push button portion 8 protruding from the hole 7 of the slide knob 3 is pushed in to push the erroneous operation prevention plate 4 against the coil spring 12. Then, the protrusion 9 is removed from the notch 10, and the slide knob 3 is slid to operate the switch.
