Both switches and spring frogs have a gap that may prevent them from operating properly if debris would fall in the gap. Switches have a safeguard in the way they operate. Spring frogs are not inspected on each use or have a track circuit to make sure if proper alignment. <br /> <br />I don't remember mentioning a power frog. I have seen a power frog that was associated with a power switch on the Indiana Harbor in Chicago. I suspect they are rare.
