For reasons beyond understanding, I'm trying to source an industrial limit switch to control the power to a desktop PC. It's run on a switch mode standard computer PSU. Most of the limit switches I've looked at are rated 5 amps @ 220 VAC. But they also have an AC-15 rating usually much, much lower, perhaps as low as 0.2 amps. I think that AC-15 applies to electromagnetic loads. Does this include PCs? They don't have much in the way of transformers... Otherwise, how can I use a limit switch for controlling my PC?
