Disassembly
Carefully remove the clothespin. To do this, remove the cover and unscrew the bolt holding the clothespin. Then we extract all the giblets. This is the board, speaker and Light-emitting diode. We don’t tear anything off, we just pull it out so that all the wires remain in place. There are two switches there. One on the board that turns on the entire device. The second one is smaller, stands separately from the board, and turns on when a fish bites.
Rework
We unsolder the wires from the second switch and solder them to any other. A switch that turns off when you remove your finger will work. Here it is important to solder long wires, in my case 15 meters. You can take a thin wire, 4 millimeters. Then solder Light-emitting diode. We don't need him. Of course, you can leave it, but it is of no use, since it does not shine brightly. You can try to connect the paw through a transistor, but this is unnecessary fuss, I did not do this. You can also connect the speaker through a resistor if you find the sound loud, but I was fine with that, so I didn't do that either. All that remains is to push all the parts back into the housing, bringing out the wires for the switch.
Then I taped the frame to the wall above the door. Then I pulled the switch to the desired location and glued it with super glue. Everything works, so I didn't mess anything up.
