Help me!!! tie buttons to BU0836A

[Sérgio Sá]

Hi.

I need your help because my experience with electronics is almost null! :frown:
To a time I bought the Ultra Precision Joystick Controller BU0836A here http://leobodnar.com/products/BU0836A/ and these buttons http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250698092857!
My doubt is how tie them. Can they do to me a drawing / diagram from as it will tie at least 10 buttons?
It wanted to add some buttons to my G25 and to do a buttonbox!

Thank you.

Sorry my bad english

Hi Sergio:wink:

No problem mate! Ok, most switches of this type, you will only need to use the OUTER two connection posts. One will be for negative/earth (-) the other for positive (+) it does not matter which way round CONNECTIONS TO THE BOARD BELOW! just click to enlarge! This will connect 12 buttons

Hope it helps, if not let me know

Thanks by the explanations!
Now leave to see if I realized! Is it so?

Are the connections what I created in the image well?
Still do not get for the buttons to work!

Evan that second diagram is amazing. Just the thing I have been looking for. Thanks for sharing.

No problem. If you guys want a better one, I have a full color and cleaner version I could scan in. I forgot I had it with my other Bodnar boards. I have an abundance of these things from buying used off forums! =]

Here is the better one.



To explain this, I will explain 1 input. Input 1 goes to Terminal 1 which goes across all of the connections. The leads from button 1 then go to the first connection on terminal 1 and terminal 7. Do this over and over and it is done.

Hi Sergio!

That should work, it all looks correct, so Im guessing you may need to use the middle connector on the switch as an earth. Try that first and let me know!
