Not that I've ever heard of. The only safety switch I can think of would be the fuel pump cutoff, but you said it's getting fuel. There's a clutch safety, but it's turning over.
Have you tried starting with the throttle open a bit?
If not, do so. It may be as simple as the idle being set too low.
Try spraying a little bot of starting fluid into the air intake. If that starts it, we can go from there to get it running and starting good.
If you can, look inside the valve cover to see if the rocker arms are moving. This is a horizontally opposed engine, so this might not be easy to do. If you can look in, but the rockers aren't moving, you have a timing belt issue.
