What Is Safety Key in Treadmill & How it Helps?

The safety key for the treadmill is a magnetic key connected to a clip. It serves as a circuit breaker. One end of the key, featuring a magnet, inserts into the console, while the other end is attached to a string with a clip secured to your clothing. If you struggle to maintain the treadmill speed, the buckle on your dress pulls off the key. This action removes the magnet from the console, activating the safety switch and shutting down the treadmill.

When you place the safety key on the treadmill, the magnet in the key triggers a small metal switch in the console. This switch completes an electrical circuit, which allows the treadmill to start.

When the key is inserted, it completes an electrical circuit, allowing the treadmill to start. If the key is removed, the circuit will break and the treadmill will stop.
