If you want zero hysteresis consider a standard, photo-transistor opto-slot and feed it into an op-amp wired as a comparator.

Hi Robin,

Great advice robin, thou you might as well be talking Marshen if folks are not into electronics:rofl:

Don't belive James/Luke are into electronics to that level, did consider suggesting opto switch's but didn't want to cause info overload.! . . . simpler to just say use good switch's and warn of the dangers of cheap bad switch's I thought.:question:

I've considered using opto switch's on my machine when the existing switch's start playing up. . . Thou I'm a bit unsure if they'll be ok due to flying debrie passing the opto falsely triggering switch.? . . How do they handle flying Ali chips.?

My machine must hold the world record for slinging chip's.! . . . They even make it into the house 20yards away.! . . . Thou my boots may play a part.:naughty:

Well, in Martian...

Probably need photo-diodes to pick them up if they have any speed, here's the circuit :heehee:

He he spelling ain't my thing.:whistling:
