    TOK what brand is that and is it still just a mechanical contact?
    Andy on the machine that I am referring to, the Dalla Corte Mini, that's where the factory puts their triac board and I seriously doubt that the components on there are rated any higher. The one I referred to was merely an example of an a.c. triggered unit not necessarily what I'm going to fit to my machine.

      Also remember please, that working on 240V AC equipment is illegal in some states unless you are both suitably qualified and licensed. In any event, at the very least you should have your handiwork inspected and tested by a qualified and licensed person before plugging it in and using.

      240V AC can and does KILL...

      Thanks for all the feedback guys. IF I was going to proceed with such a mod, I'd have the techs at my machine service centre look into doing it. They have already offered to have a look into it if it was something I really wanted to consider, but "all care, no responsibility".

      btw, the Machine is a Bezzera BZ99S DE Volumetric.

      Whilst the ~5 second 'click on', 'click off' cycle doesn't particularly cause me grief (I've had this machine from new for 4.5 years), there's already too much noise in the world, so I've always wondered why electromechanical switching was used instead of an SSR.

        1. Machine builders are conservative and tend to go with what they know
        2. Mechanical relays are CHEAPER
