Low voltage to vacuum

Hi folks, I'm new here and know little about low voltage and electricity for that matter. What I'm doing is installing a product called a "VACPAN" in my RV. It's basically a kick plate that you sweep dirt into and is connected to a central vac system. When you kick the lever it activates the central vac and opens the flapper and sucks away the dirt. Since i dont have room in my RV cabinet for a real central vac system, I want to install a small portable vac like a porta power Hoover in there and connect the activation wires from the VACPAN to the on/off switch on the Hoover. The instructions on the VACPAN says to "attach low voltage wires to \vacpan terminals marked "low voltage only". So what is low voltage. When I put a voltmeter on the contacts on the switch on the Hoover, I read 120. Will I fry something? And how can I reduce the voltage if that's whats necessary. Thanking you all in advance for any suggestions.

You would need to build a small control panel using a recepticle and a low voltage switch.

You cannot connect the 120 volt from the vacume switch to this system

They make switches for closet lights that are loop powered. (meaning you do not need a transformer.)


Install a recepticle in a box and use this relay to turn off and on the entire recepticle. Then just leave the vacume switch in the ON position.

central vac units (home and rv) have a low voltage relay built in.
It's so you dont need 120v flowing through that switch (yikes!).
With your head unit you dont have thus so you will need to wire in your own. The relay uses low voltage (12v would be ideal in the rv) to switch on the 120v to the head unit. jwhite had a good suggestion.
