12v DC relay question...

I have one of these in my motorhome, on the trim piece under the steering wheel hooked up with a 30 amp relay hooked to the chassis battery. I didn't want it wired to the ignition and since it has a LED that is always on, I wired it with a 15 amp switch.

I was thinking of putting another one on the passenger side of the dash. Since it only pulls 5 amps, would it be okay to share the 30 amp relay and the 15 amp switch for both outlets?

Thanks,
