Saved my workout routine

My treadmill was useless without this part. This universal switch key brought it back to life instantly. The build quality seems robust, and the clip attaches securely to my waistband.

Essential safety part

Bought this as a spare just in case. It's reassuring to have a backup safety key. The square shape matches the console slot perfectly without any wobbling. Highly recommend keeping a spare.

Works well, cord is a bit stiff

The key itself works exactly as it should to stop the machine immediately. My only minor complaint is that the coiled cord is a little stiffer than the original, but it hasn't affected performance.

Fast shipping and good quality

Arrived quickly and was exactly what I needed. The magnet is powerful enough to stay attached during vigorous running but pulls off easily in an emergency. Very satisfied with this purchase.

Perfect fit for my Yijian Elf

I lost the original key and was worried I wouldn't find a replacement. This square magnet fits perfectly on my Yijian Elf treadmill. The magnetic hold is strong, and the clip feels durable. Great value for the price.

Good but color varies slightly

Functionally, it works great. However, the red color is slightly darker than my original key. Not a big deal since it hangs off the side, but worth noting if you care about aesthetics.

5 FAQ

Q: Is the cord replaceable if it gets damaged?

A: The cord is integrated into the unit for safety integrity. If the cord becomes damaged, we recommend replacing the entire safety key to ensure reliable emergency stopping.

Q: How strong is the magnet? Will it fall off while running?

A: The neodymium magnet is designed to be strong enough to remain attached during normal running conditions but will detach immediately if you fall or move too far away, triggering the safety stop.

Q: What are the dimensions of the square magnet head?

A: The square magnet head measures approximately 2cm x 2cm (0.8in x 0.8in), which is the standard size for Yijian treadmill safety switches.

Q: Will this work on the Yijian Elf Pro model?

A: Yes, this square safety key is compatible with the entire Yijian Elf series, including the Pro models, as they share the same magnetic switch interface.

Q: Does this come with a clip for clothing?

A: Yes, the package includes a durable plastic clip attached to the end of the cord, designed to secure easily to your waistband or shirt.
