Now that I've found an adaptor to connect my Wickes/Earlex vac to my circ
saw, I was wondering...

You can get vacs with a socket outlet on, so you can plug a power tool into
it. When you start the power tool the vac switches on, stopping the power
tool switches off the vac.

I assume some kinda electronic gizmo senses the load and does the switching.

Can you buy said gizmo to fit to an existing vac?
