Quality product. I'm a workshop instructor and have actually used these switches to turn machines on and off each day before starting classes or leaving for the day. The key was a bit fiddly trying to figure out how to put it in the slot but once I got the hang of it and did it a few times it's ok now. I like the fact that I had to practice where and how the key fits, so it would be difficult for someone I didn't want to flip the switch to turn on the machines.
