Steve,
The only "single action" things I know much about were originally patented by Samuel Colt, and I love them all.
This building has beautiful lobbies with keypads in each (usually reading an error code).
This is the same building that has the 225 amp fuses in the 200 amp disconnects.
I absolutely hate when I'm sent here. I wish that I could just fix it...but it's not my building
