PC and CRT power switch in 1 happ pushbutton?

[whitiex]

I have a smart power strip that will turn the tv off, but the tv doesn't automatically come on when power is restored.  I know how to put the PC power switch to a happ pushbutton.  but can i wire the CRT tv power switch to the same pushbutton?  Thanks for any help!

You've probably already done this, just asking to be thorough.

Have you checked menu settings for "power on resume"?

Have you tried turning the TV on then unplugging it and plugging it back in?  On some models unplugging it puts it into auto-on mode, which then allows you to use the smart strip -- several threads on the topic a while back.

IIRC some people have even wedged the TV/monitor power button closed with a toothpick so it's always on.   

There are also diagrams in other threads that show how to wire a DPST ot DPDT momentary switch so you can switch on the TV and computer at the same time.  Unfortunately, Double Pole microswitches are very rare, but you might be able to make a leaf-switch stack like this:

Computer1
Computer2
Insulator
TV1
TV2

Maybe RandyT from GGG can add something like this for his ClassX buttons? 

He might not move a lot of volume on them, but it would be a really cool option.

Assuming your going to open up the TV and modify the on/off switch, you could either try shunting the switch so that the connection is always made or you could wire a double pole double throw relay (DPDT) relay off your power switch so that one set of contacts goes to the PC power and the other contacts would be tied to the TV power switch

there is no power on resume setting, it doesnt turn back on after being unplugged,  and holding the power button down doesn't work.

whitiex,

Since your TV will not power on with the button held down, you're going to probably have to do what mgb recommended using the DPDT relay.

[PL1]

That leaves you with a DPST or DPDT switch/relay wired like this.

You add the green switch and red wires to the existing circuits.

The TV and computer circuits are mechanically connected, but electrically separate.




If you are worried about modifying the board, you could scrape back a little insulation and use micrograbber clips to connect.

so i can have +/ground from the pc and tv plugged into the same connections on the pushbutton.  that is what i am looking to do

If by that you mean connecting both power-switching circuits to a single-pole (arcade-style) microswitch, that is a really bad idea.     It might damage your equipment . . . or worse.   

If you mean that you found a DPST (Double-Pole Single-Throw) or DPDT (Double-Pole Double-Throw) pushbutton that you plan on wiring like the diagram, then that's great.

Another option, if you happen to have an LED-Wiz in your future, would be to run wires from the momentary switch on your monitor to a tiny relay controlled by an LED-Wiz.  Then just issue a command to turn on the monitor at startup, or after your front-end is loaded.

I've got the grounds for 2 tvs and the pc all tied together on one side of an arcade button microswitch and the signal wires to all 3 components on the other. I wouldn't have believed this was possible, but with the advice of shakenbake, I tried it and it works fine. The one thing I notice is that you want to press the button for over half a second when turning on and off.

Combining the control circuits of 2 separate devices?
 I wouldn't advise that. Maybe it will work for some but not in all cases and with all equipment.
For the low cost of a proper relay and the simplicity of wiring, why not just do it.

If that sounds too complicated, then why not just wire your power button to the TV and have that plugged into the control outlet and plug your pc into one of the switched outlets and set your pc up for resume after power loss.
Or
  Wire a relay off of the PC power supply so that the contact closes after the PC powers up and turns on the TV.
There's multiple ways.

I'd like to hear what RandyT thinks about using a ClassX button with 2 True-Leaf Pro switches, longer mounting screws and an insulator (strip of milk jug?) between the switches for this application.

Looks like the upper switch could be mounted in the normal position (shown below) with the insulator and lower switch underneath.

The lower switch upper leaf could be bent until the insulator just touches the lower leaf of the upper switch.

Then the lower switch lower leaf can be bent as needed.

When the plunger is pushed, the upper switch leaves, insulator, and lower switch leaves bend until both switches close.

Or you could use a button like this: (Not a Happ, but close)

Never mind, these switches have a NO NC contacts, and you will need two NO. (Plus the link is not the switch I linked to)
Search the site though, they may have what you need.

Sounds like this would work fine, so long as all of the mechanics of it work out.  This type of stacked arrangement with leaf switches is fairly common.

[mgb]

I like the idea of stacked leaf switches. You can use a small nylon spacer between them in order to link them for activation.

thanks for your help.  i think i will go with a DPST switch.  but i noticed most are toggle switches.  what if i want to turn everything off via proper pc shutdown w/ smart power strip?

[mgb]

You'll want to use a momentary switch.
There are plenty that are momentary.
