Rob I see the trouble with this is starting the machine code with the switch not in the correct position and then not getting to the Osh#t button fast enough

I agree, but when you have done it a couple of times, you learn. I check the switch is in the correct position, but the 'always on' position is down, so you can hit it faster than the osht in my case. After having my finger bitten by the machine, it also helps my confidence to put it to 'off' whilst doing a tool change and restarting the code does not fire up the spindle, so I switch it to 'on' before continuing. My new Cam software puts out the M03 after a tool change though.
