Hi where can I find a regulator switch to put on my vacuum pump ,so when its up to the required pressure it switches off automaticly and switches on when required . 

Hi AHA,

I have been looking into creating something like your describing when I get time.

It would have been handy, had a mould surface breach in a tiny place, after the infusion even after pre testing for vaccum.
Had to baby sit it for hours as I don't like leaving the pump running constant, but I do have a degassing chamber attached to the line to act as a vacuum air pig.

RS has a range of adjustable vacuum switches, this norgren switch operates in the -1bar to -0.2bar range.

Hope helped.
