るものである。 Next, the installation of the printed circuit board 6 and balancer 21 prepared as shown in FIG. 3 to the lower cabinet 20 will be explained. The printed circuit board 6 has each terminal 11~
18 into the holes 30 in the lower cabinet 20, hook the other end onto the hook 31 of the hook 23, and attach as shown in FIG. As a result, the printed circuit board 6 is positioned by the ribs 26 and 26', is supported by the ribs 22, is held by the ribs 24 so as not to shake, and is further held between the ribs 22 and the claws 31 of the hooks 23 and moved up and down. It is fixed so that it does not occur. On the other hand, the balancer 21 has a hole 32 through which the boss 25 is inserted, as shown in FIG. The balancer 21 is supported by a rib 27' extending from 25, and is fixed to the boss 25 with a screw 28 via a washer 29. As the balancer 21, a heavy and thick plate must be used in order to maintain the balance of the weight before and after the switching device, but in this case, the balancer cannot be processed by press processing, so this embodiment We use multiple plates with a thickness that can be press-formed. The rib 27 connecting the boss 25 to which the balancer 21 is attached and the rib 26' is connected to the balancer 21.
This is to prevent the printed circuit board 6 from coming off and the ribs 26' and the hooks 23 from being damaged by regulating the height of the ribs 26' and absorbing the force in the direction of arrow D shown in FIG.

る。 As described above, according to the present configuration, simply by fitting the printed circuit board 6 into the lower cabinet 20, the printed circuit board 6 can be positioned and mounted in the front and rear, left and right, and up and down directions, so that the work efficiency is extremely improved. Further, since the balancer 21 is obtained by press working, it can be constructed at a very low cost. Furthermore, this allows for a significant reduction in assembly man-hours and costs. Further, the rib 27 restricts the position of the balancer 21 in the height direction, and also prevents the rib 26' and the hook 23 from being damaged and the printed circuit board 6 from coming off. Although the present embodiment has been explained in the case of a high frequency signal switch, the present invention is not limited to this and can be applied to other devices.
