Hello All About Circuit Folks
If I am asking a question answered before, I apologize, and I would appreciate the name of the thread or link so you don't have to go through explaining again.
I am sure I could "hack" it, but I have a small machine shop and can fabricate a key if it is simple enough, which I suspect.
I cannot find a pic of the key anywhere. Do any of you happen to have a key like it, and possibly post a pic? Or do you happen to have a pic or know where I could find a pic?

Thank you so much for your help

It is the same sort of switch as the one used for institutional lighting, like in schools, to prevent tampering. I looks like a Hubble but I don’t know if the dimensions are the same. But you can see the principle: the two “tines” fit the actuator and the covered tracks on the edges let them pass while shielding against operation with a straight tool.
