A pair of engaging protrusions 7 are formed at the upper and lower ends of each insulating barrier 5 so as to be separated from each other. The base end 7a of the engaging projection 7 is formed in a constricted shape (see FIG. 4).

12の基端部12aはくびれて形成されている。As shown in FIGS. 2 and 5, upper and lower insulating barriers are provided between the side insulating barriers 5 in the upper and lower portions of the main body case 1.
10,11 are supported. A pair of engaging holes 12 are formed at both corners of both insulating barriers 10, 11 so that the engaging protrusions 7 of the side insulating barrier 5 can be inserted (see FIG. 3). The edges of the insulating barriers 10 and 11 between the entry holes 12 are bent inward to form contact portions 15. The engaging hole
The base end portion 12a of 12 is formed to be constricted.

付け方向を除いて開閉器内部が覆われることになる。The engagement protrusions 7 are engaged in the respective engagement holes 12, so that the upper and lower insulation barriers 10, 1 are provided between the side insulation barriers 5.
1 is supported. The engagement between the engagement projection 7 and the engagement hole 12 is prevented by the constricted base end portions 7a and 12a. Further, the abutting portion 15 abuts on the outer surfaces of the upper and lower end portions of the side insulating barrier 5, so that the upper or lower insulating barrier 1
0 and 11 are reliably supported in the direction orthogonal to the side insulating barrier 5. The inside of the switch is covered by the side insulating barrier 5 and the upper and lower insulating barriers 10 and 11 except for the mounting direction of the bushing 2.

I don't need it,
Since the number of them is small, the work of assembling the insulating barrier of the switch can be simplified.
