Wow, I cannot imagine how I missed that, considering it says momentary on every single switch description. I think my brain was just imagining how cool it would look on the side of my rig. Anyway, I was thinking it would be nifty to have a somewhat waterproof industrial type switch mounted on the front just below my non direct heated MLT.
I guess I will look around for some button cases. I don't mind shelling out some cash for it since I will only have one button for a single March pump.
In the meantime, maybe I will get one of those momentary switches for my garage door.
