Need Device to Keep electronics off when power comes back

Is there a device that will keep my electronics OFF when the electrical power comes back?  My electronics (a Music Server, DAC and integrated amplifier) will turn back on when the power returns if they were on when power failed.   I do not want them to turn back on, on their own, when power is restored.   This is because often when power fails, it will attempt to restore power several times and then fail again.

I am looking for something that I can plug the unit into and then put this into the outlet.  Does such a device exist?  I am looking for a breaker box that will trip when power fails and require resetting manually.   In other words, when electrical power is stopped, all my electronics will be shut off until I manually reset them.

Furman reports "they do not make a product like this.   All of our products will come back on after a power outage".

The TRC-Shock Shield protection switch, mentioned above, works perfectly.

When electrical power is removed, the connected device shuts off.  When power is restored, the device remains off and the switch on the TRC Switch must be pushed so the device comes back on.   Very cool.

Unfortunately, Northern California is having very high winds and our Utility Company (PG&E) May turn off the Electrical power at any time.  This warning is for today and Thursday.  To be safe, I disconnected my audio system from the power grid.  

In fact, the tunnel between Contra Costa County and Alameda County May have to be closed.  They cannot allow vehicles to pass with no electricity.

Several people have asked me about the TRC-Shock Shield protection switch. 

The major advantage of this product is simple. When there is a power failure, this device SHUTS off the power. It requires you to “manually” reset it to return the power. As you know, the power goes off AND comes back on AND then off again. This on and off switching of your audio equipment is not good.

Unfortunately, this is especially true in California at this time.

I purchased 3 TRC devices. I have 2 for my main audio system and one more for my home theatre system. I tested it with a lamp and it works perfectly.

Highly Recommended.

Thanks go to @snapsc for recommending the TRC-Shock Shield protection switch.

Keep safe out there. I read that crazies from middle America were setting fires deliberately in CA because they hated liberals.

Hey, this is easy.

Just get a relay, one big enough to run your gear and has at least three sets of normally-open contacts.  And a pushbutton and some outlets.


Power your gear through two sets of contacts and connect the third set across the pushbutton.  Place everything neatly inside an appropriately-sized enclosure like DIY guys use.

Plug it up.

When you push the button the relay closes and powers up the outlets to your gear.  When you let go of the button everything stays connected because that third set of contacts is across the button and they're closed too.

When the power goes out the relay drops out.  You may push the button again whenever you want after the power is back and you've turned all the equipment off.
