for dorm prima parts

Hello There,
I live in a dorm with 2-burner stove. This has inconveniently in the middle at the front edge on top the control buttons, where you similar even in passing with the pants pocket can get stuck.
After me, this design has recently brought an apartment fire of experience, I looked around for an alternative, and these buttons ordered with child safety in spite of the poorer reviews ... and they are great!
Yes, for me it does not close all the way down from, but I think that frankly to clean fine;)
the thick top of the knob is idle rotation and only the lower ring with the numbers is the actual switch. I think it is a reliable protection against another house fire!

Conclusion: as a fire prevention appropriate fine in my opinion. Child protection I can not judge)
