Circulating pump speed contrl Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

I'd be really grateful if someone could explain how the speed control switch works on my 3-speed pump.
By that I mean how it works electrically and the components used and what they do.

(I'm happy with electronics but not so great at induction motors). :?

Thanks.
