Treadmill is a routine equipment in family and gym, and it is also the simplest one in family fitness equipment.
During exercise, one end of the magnet is adsorbed on the treadmill panel, and one end of the clip is clamped on the clothes. When running on the treadmill, the speed of the treadmill can't keep up. When the body retreats, one end of the magnet will inevitably leave the panel, and the running opportunity will stop immediately to avoid danger.
When one end of the magnet is not on the panel, the treadmill cannot be started.
Therefore, this safety switch is very important and must be properly kept.
