Micro switch is a small contact interval and fast moving mechanism, with a specified stroke and the specified force for switching action of the contact mechanism, covered by the shell, the external drive rod of a switch, because the switch contact spacing is relatively small, it is called the micro switch, also called sensitive switch.
Use the soldering iron and the tin wire to connect the three feet behind the microswitch,with this reheating ,Those tin can be heated at the same time, To achieve the purpose of melting together, after connecting the tin, stop for a while, and then use tweezers to grip the top of the microswitch, and heat the solder joints of the back three feet again, you can slightly move the iron head laterally, after the tin of the three feet is melted, Gently bend a little to the front of the micro-switch, so that the three feet behind the micro-switch are raised by about 0.3MM, but do not force too much, and then quickly and repeatedly heat the two solder joints in front of the micro-switch, while the solder joints are melted, bend a little Angle to the back of the micro-switch, so that the two feet in front of the micro-switch are just separated from the welding pad. Finally, heat the back of the three foot solder joints, bend forward at some Angle, and remove the micro-switch can be smoothly taken off.
