Adding a Central Vacuum Remote Control

I have a central vacuum cleaner where you close a switch on the hose outlet to start the motor. I would like to use a remote relay switch with a button attached to the wand to turn it on and off without going back to the outlet.

My remote switch requires power to operate and really seems designed for simply turning the power on/off to load rather than closing a circuit to a relay.

Will my proposed solution in GREEN work? I would actually connect the ground to the ground on an outlet near where I will place the switch and not to the the original outlet powering the central vac - but ground is ground right?

I would also like to retain the functionality of the existing switches. Or would there be a problem if they were both turned on at the same time (I think not but I need to ask).

One draw back I see is if the remote is activated without first confirming that the hose is present in the outlet, if it is not the motor will over speed and over heat.
Operating them in parallel does no harm.

Got it mine is a hide-a-hose so there is always a hose present.

That was great - thanks for the quick answer.

So using a ground wired to any nearby (to the remote) will be fine right???

As long as it is only used as a earth ground reference and not connected to, or as, a working conductor, although that may not really be a problem, depending on the Vacuum unit LV system. Which is most likely totally isolated.
