I installed 6 of these switches in some custom manufacturing tools for my company. One never worked, and I pulled it apart and found that one of the contacts was half missing, as if it had been punched out of the edge of a sheet of metal. Two more have broken during use; both cracked and fell apart at the back, causing the light gray piece (seen in the pictures) to fall out.
As others have said, these switches are not keyed at all. You could turn them with a small screwdriver, coin, or possibly fingernail (though I haven’t tried the last).
Even the switches that are working feel very cheap, and sometimes have to be turned back and forth a couple times before they make contact.
I’m a fan of SparkFun, but this particular product is pretty lousy in my experience. I wouldn’t recommend buying it.
No public wish lists :(
