The mounting is completed by being press-fixed between the press tube 16 and the press tube 16.

Note that the receiver 20 is removed by performing the procedure reverse to the above.

In other words, hold the handle 29 of the receiver 20, push the receiver backward and lift it a little to remove the end of the mounting pipe from the latch 15, and then pull the receiver forward by holding the handle. If it is removed, the mounting pipe 19 on the receiver 20 side will come off from the supporting guide pin 12 on the switch side, and the receiver 20 will come off.

Effects of the invention As described above, with the present invention, when a bypass switch is installed at a high place on a utility pole and a receiver is installed on the bypass switch, the supporting pipe on the receiver side is used for mounting on the switch side. The receiver can be installed extremely easily by simply fitting it onto the guide pin and pushing the receiver backward.

In addition, the attached support pipe is always pressed and fixed to the latch with a constant force by the pressure tube that is urged toward the tip of the guide pin.
Even if vibration or impact is applied, the support pipe will not come off the guide pin, and a secure attachment state will be maintained.

Also, when removing the installed receiver,
While holding the receiver and pushing it back once,
By slightly lifting the tip of the mounting pipe, the mounting pipe on the receiver side can be easily unlatched from the latch fitting on the tip side of the support guide pin on the switch side. It has the advantage of making removal work easier.
