Need OCN pro's Help!! Circuit board question-

post #1 of 16
Thread Starter 
Hey guys-

I know someone here at OCN can help me with this small problem I am having.

Heres the deal- I have this usb 2-port manual switch that I use to connect a Logitech G27 steering wheel to a pc and a ps3. I use the switch so I dont have to unplug the usb from one and plug it into the other one. Heres a picture of the manual 2-port switch.




after taking apart the plastic housing with a flat screwdriver, here is the circuit board.




I want to use a 3 position toggle switch (on-off-on) to control the usb switching instead of the plastic box/buttons. I need help on where to solder the wires from the 3 position toggle switch to the circuit board.

The two buttons are connected in a way that when you push one in (on position) the other button pops out to the off position. there is also a position in the middle where neither device (pc/ps3) gets the signal.

I could really use some help with this and your help will be greatly apprieciated!

Please OCN members come to my aid!

Not going to happen. If you look, you can see that the plastic buttons make contact with two sets of six pins, thus making the electrical connection for the USB on or off.

A simple on-off-on switch will just not work.

It can happen. He would need a 6 pole, triple throw switch. Or 6 single pole, triple throw switches that he would try to switch all at the same time. First idea is fine if such a toggle switch exists, but the second idea could be bad since it would be hard to switch all 6 simultaneously.

it just so happens that the 3-way toggle switch that I bought has 6 connections on the back. here's a picture of the switch- you cant really see it in this pic, but there are 6 connecting points on the toggle switch. Need help please!

But you need twelve total.

I got the impression he was hoping to do it with a single switch. It would be more complicated but to do it with a single switch, you would need that switch to turn on a bunch of relays so flipping one switch in essence flips 6 more contacts on or off.

Not if there are triple throws, aka three positions.

A single switch would have to have 6 poles on it, aka 6 isolated connectors. I don't know of a toggle that has that many poles on it. Yes, using single switches would be complicated and there could be problems if half of one side and half of another side are switch intermittently.

If you look on the switch box, it says "DPDT" which means double pole, double throw. So that switches two connections in to two different positions. In that case there would be no 'off' position. You would need 3 of those, and I would advise against that.

I honestly don't see why you want to replace everything with a toggle. The current setup is ideal.

EDIT: here is a 6 pole 3 position rotary switch http://www.rutubes.com/index.php?productID=297
Something like this would work, but again the current setup is ideal.

hey guys- thanks for taking the time to think about this with me.

The 2-port usb switch works great. It does exactly what I need it to do. The problem is that it is ugly and the buttons feel cheap, and it has 3 usb cables running to it, and I cannot integrate it into the dashboard that I have made. A single toggle switch would be ideal in my situation, as long as it achieves the same operation.

I got home and was taking a look at the circuit board again.
I think I see what is going on and here is a picture to illustrate what I think is happening.
Feel free so correct me if you see anything wrong with what I have seen-



the arrowed lines come from the pc and the ps3 and provide 5v power to the usb device (G27 wheel) that I need plugged into both systems. the solid line represents the usb path from the G27.
My color code is-
black = ground (common)
red = +5v
green = data+
white = data-

I'm pretty sure that the uncolored solder points on top of the 6 point clusters are not connected to anything. You can see on the top right side 6 pin cluster, there is nothing there on the circuit board.

The yellow lines represent the connections that are bridged when the buttons are pushed (one side at a time- depending which button is pushed)

A USB cable only has 4 wires. Ground, +5v, Data+ and data- Why would I need a switch with 12 poles? I would think that 12 would work for all four wires on a usb cable if the opposite sides (a/b) used a shared ground (like the switch I have).

The switch I have is a 3 position switch with the center position being 'off' for both the a and b side. there are 2 poles for each side, so you can effectivly make/break connections on 2 separate wires for each side (a/b) the middle connections of the 6 connections are common relative to their column

something like this-
a1 a2
g1 g2
b1 b2
the ground connection is shared by both the a and b sides, so there will be 2 wires connect to each of the ground posts, and 1 wire to each of the a and b posts.

I can see why the +5v connection needs to be broken, because I dont want the pc pumping 5v into the ps3 usb port or vice versa, but it I use the switch to make/break connections on the 5v and one of the data wires, would that work?

example- to kill power to a light bulb, you only need to break one connection, example disconnect the positive lead to the light, and it will be dark. you dont need to break the negative connection also.

so if I break 2 out of the four wires that make up a USB plug, wouldn't that effectivly break the connection?

Thank you for your consideration in this matter. Rep given

actually having the PC or the PS3 on together wouldn't do much, because it would be 5v+ to 5v+, it would be like combinding two power sources into one. They would work together, not against eachother.

You would only need to switch the USB data wires in order to make it work.

Here's what I think I will test. using this picture, I will use the A side of the toggle for the 5v connections, and the B side for the data+ connections. I will then use a couple bits of wire to bridge the data- connections (this part I am not sure about, if it will work with them being bridged). the ground connections dont seem to get broken with the switch, so I shouldn't have to do anything to them.

EDIT this picture is wrong- the bridge on the right hand side needs to be swapped with the 2 pins right next to them so both bridges are on the left side of their respective clusters-




SWITCH CONNECTIONS

is this true? both pc and ps3 have +5v power leads coming from their usb ports- if you connect 2 positive wires, you get a spark right?
