Unusual use of M8/M9 to control a compressor

Perfectly viable.

Although anything that bypasses the switches (e.g. my first post) takes the manual switches out of the equation. I'd look at the installation effort.

Thanks. As one of the 2 way switches is next to the compressor and power supply the installation effort is easy regarding mounting the relay, the wiring may take longer due to my electrical dyslaxia!
