you may have already gotten a reply, but the switch also has an integral circuit breaker, so it is more than just a switch. I had mine turn off once due to a power surge. the line fuse is a sort of last resort safety thing, the power switch will click off first usually. just replace the switch and that should solve it. I wish I could tell you where to get a replacement, but I'm sure astron can provide one.
73 and good luck
