The computer mouse wheel has become poorly working. How to fix this

The computer mouse, namely the scroll wheel, started to "glitch". If you

scroll the wheel down, the cursor on the monitor screen will jump up and down, this also applies to scrolling the wheel up. At first I thought that the problem was in the

radio channel, because the mouse has a Bluetooth system. I brought the mouse closer to the receiver and

the same thing, I also checked the 1.5V battery. As a result, having disassembled the mouse, it became

clear that the problem was in the wheel itself. It is a contact with the

slider, which can become dirty or oxidized over time, or

the contact can loosen. I solved the problem simply, I took and replaced the encoder

with another one from another mouse
