I need a wireless remote speaker on/off switch (stereo). This $200 item does the job, but has features I'd never use: ATM 7-Zone Speaker Selector with Remote Control
The switch is for auxiliary speakers; the primary speakers are always connected. In effect, I need only a remote controlled DPST switch rated 6A, to open/close one conductor per each speaker.
Could someone design a DIY circuit for my application? The remote requires only one function, open/close (on/off). Could an old laptop SMPS supply the required power?
I realize a receiver or integrated would work, but in this application the same amp must drive both sets of speakers.
Thanks.

Do you mean this?
Etekcity Remote Control Outlet Wireless Light Switch for Household Appliances, Unlimited Connections, FCC ETL Listed, White (3Rx-1Tx) - Electric Plugs - Amazon.com
I presume the wall appliance employs mains power for the receiver and switch function. Could you please explain better what means, "replace the relay with a DPST?"
Thanks!

Yes, that's the sort of thing I first thought of hacking, but there are easier ways.
Have a look at something like this:
Amazon.com: INSMA 433Mhz Wireless RF Switch Long Range DC 12V 4CH Channel Wireless Remote Control Switch, DC12V Relay Receiver Module, Transmitter Toggle Switch RF Relay (2 Transmitter & 1 Receiver): Home Improvement
or this:
ELENKER DC 12v 10A relay 1CH wireless RF Remote Control Switch Transmitter with Receiver - - Amazon.com
As you stated, you need to switch 2 poles, so look for something like that. If you have a common ground, you could switch just the ground, so a STSP would do. Seems to be a lot of those on Amazon.
