I need to replace a bit of a mess of a DOL starter / overload / pressure switch system on an old 7.5HP compressor with something new that works! Many thanks due to Tony who's pointed me on the right path, it's occurred to me that as there are lots of compressors in the world, there might also be someone who makes controls specifically for this purpose and save me the bother of fabrication at a time when I can barely pause to wipe my arse. Anyone know? I've looked around on the web without much success.
