The PCB dedicated satellite shaft is fixed on the PCB circuit board, not on the steel plate. The transparent satellite shaft is designed to be relatively compact, ensuring it will not loosen during use. Due to its compact structure, the tactile feedback is particularly noticeable. Installation: The satellite shaft is installed on the PCB and must be tested for smooth operation to ensure there is no jamming. After testing, it should be lubricated for optimal performance.
