'From the projection 35. 1
Reference numeral 03 denotes a cover piece detachably formed on the cover 4 to open the main switch 2.

According to this embodiment, the connection to the connection terminal portion 9 on the input side of the main switch 2 and the connection terminal portion 17 on the output side of the branch switch 3 is performed by connecting the electric wire from the wire portion 11 of the housing 70 to the electric wire. Is drawn into the housing 70, and is performed using the wiring spaces 85 and 86. In this case, since the wiring space 85 of the main switch 2 is made larger than the wiring space 86 of the branch switch 3, the size of the housing 70 can be reduced without making the wiring work of the main switch 2 difficult. The main switch 2 and the branch switch 3 are connected to connection conductors 19 and 1 including a bar 18.
Since the connection can be made by 9 ', a large space for wiring work is not required.

A recess 80 for forming the wiring space 85 is formed at the end of the main mounting body 2 to connect the main mounting body 2 to the branch mounting body 3 and to form the main mounting body 2 and the branch mounting body 3. Since the side opposite to the connection side is attached to the housing 70, the mounting operation is simplified as compared with the case where the main mounting body 2 and the branch mounting body 3 are individually mounted on the housing 70. Further, the connecting side of the main mounting body 2 and the branch mounting body 3 has overlapping portions 80a and 90, and the overlapping portions 80a and 90 are provided.
a, 90 are connected by the screw 81, so that the main mounting body 2
And the branch mounting body 3 can be securely connected, and the number of mounting the main mounting body 2 and the branch mounting body 3 to the housing 70 can be reduced, so that the mounting work is simplified.

Further, since the concave and convex fitting portions 80c, 80d, 90b for positioning are formed in the overlapping portions 80a, 90, the connecting work between the main mounting body 2 and the branch mounting body 3 becomes easy. Further, since the holding piece 15 for fitting and holding the overlapping portions 80a and 90 is provided on the housing 70, the main mounting body 2
In addition, the work of attaching the branch attachment 3 to the housing 70 is further simplified.

In the present invention, the main trunk mounting body 13
And the branch attachment 22 are formed separately, but may be formed integrally. Further, although the main mounting body 13 and the branch mounting body 22 are connected to each other and attached to the housing 70, the main mounting body 13 and the branch mounting body 22 may be mounted to the housing 70, respectively. Further, the main mounting body 13 and the branch mounting body 22 are overlapped with each other by the overlapping portion 80.
Although the connection is made by a and 90, other connection means may be used.
