TomG, thanks for the info, yes I did look at the rubie probes but decided to make my own using a dial test indicator tip. It has a 2MM ball on the end so 1MM from center is easy. The spring I am using on the probe is fairly light in tension so deflection should not be a problem, specially on my machine.
The circuit is completed and tested, it consumes 20mA with LED lit and 0.002 mA in standby mode, this converts to 9 hours with LED lit and 90000 hours in standby.
I should get the circuit on the weekend so next week I solder it in and function test.
