Gilbarco uses reed switches in many of their keyboards. This is a relatively inexpensive one, but I've read that many magnetic reed switches aren't that great.
This model is very likely a magnetic reed switch keyboard
(sorry, I just looked into gilbarco keyboards a lot last month.)
I have seen at least one example of keytronic reed switches, but didn't know that's what gilbarco used until now. I think they switched to cortron for later keyboards (I haven't been able to determine which cortron switch they use int he more modern ones that have it, but the PCB is branded cortron)
