I just bought a delta unisaw 36-953 but the previous owner had
replaced the standard plug with an extension cord which they wanted to
keep. I don't know how the switch is wired internally (i.e. which
connectors to wire the 240V supply to - ground is pretty easy to
identify). Could someone take a look in a their switch and describe
the wiring or even better send me a picture?

Thanks,
Dave
