RUNJRX KEYBOARD GM4.0 - 4 Pack

The difficulty in replacing the micromovement is to remove the old micromovement. It is recommended to use the tin vacuum cleaner to remove the solder. Heating the welding time as short as possible, each soldering time is checked within 1-3 seconds to avoid excessive temperature damage to the circuit board and the micro switch. The microswitch should be close to the circuit board, there should be no holes. Otherwise, problems can easily arise, such as a shortening of the stroke and bad feeling. Finally, check if tin slag remains on the plate, to avoid short circuits.
