Good day, I have tried to find the answer to my question through various means, and I have had no luck.
My question being, what is a low voltage lock switch?
the context of the question:
"make use of a control circuit that has an extra low voltage lock switch and individual extra low voltage switches as well as a master selector switch"

I understand the circuit that I must draw out, just unsure of the function of the lock switch. I could not find anything on google regarding this type of switch. We are currently working on low voltage switching.
Any help would be greatly appreciated

 

Personally, I haven't heard of such a beast. But why wouldn't you first ask your teacher or a TA the question? They're the ones who would know what's required.

 

I was trying to do this assignment ahead of the class, and just ran into the term this evening. My teacher isn't available till monday in the am, and was trying to figure out the switch prior to that.
