Automatic vacuum switch for two circuits?

[NewWoodWorkerVA]

My single car garage workshop has two 20 amp circuits and 1 15 amp circuit.  Today I bought a 1 hp Laguna 4 inch dust extractor (B Flux 1 HP).  Rated at 8.4 amps.

I want to have things like with my CT 26 that when I turn the tool on, the vacuum comes on.

I’ve seen devices on Amazon from Ortiz’s that do this on the same circuit, at 15 amps.  They have one from IVAC that handles two power inputs and the multiple outputs but says 12 amps out. 

I have a Sawstop CTS at 15 amps and the Kapex.  I also have a 2 1/4 HP router.

I’d run the vacuum on its own 20 and the tools on the other 20.

Any suggestions on an auto vacuum switch for my situation?  Thanks

Get the Ivac autoswitch, and hook up the switch to two circuits (say 20 amp and 15 amp). I use the autoswitch with a 1HP dust collector, Sawstop PCS and one shop vac all at the same time with no issues (the d.c. and shop vac extract dust under and above the saw table). I also use another Ivac autoswitch with a shop vac using a similar circuit setup for the Kapex.
