Are these custom order only? Selling via a web store?

I'd imagine these are primarily useful where you have difficult to adjust switches. A ramp where the ball can go fast enough to miss the switch. A switch that can stop a slow ball and make it get stuck. Switches underneath ramps or a mini-pf that make cleaning ball trails a real pain.

Do these still work on wire forms? The Dialed-In right orbit shot can sometimes miss the switch on the wire ramp. But since it's already metal wouldn't that give false positives or just stay on or something?
