Diagram for wiring a SPST Tact Switch USB mod?

Youfillintheblank, Thank you very much. That is most helpful.

For this mod I believe I may need higher Tact Switches actually. But I would imagine the contacts are still the same configuration.

I will be going out today to get a multi-meter, and some 100 ohm resistors for the LED.

Cellmeister, Thank you for the confirmation of the contacts in the four legged Tact switches.

So if they are diagonal, I still do not quite understand why there are two pairs.

Thank you very much for the advice everyone. I am headed to Rad Shack now. If anyone as anymore info, keep it comin. Thanks!!

Also, I hate to sound so fresh to this, so please excuse me. What solder/flux is recommended for work such as this? I have a few different kinds, but am unsure as to what to use. I realize a smaller guage is better, but which? I have been experimenting with .032" 60/40 rosin core. Any other tips? Thank you again!

Cekte, that sounds like the solder i was using, i know it was a 60/40 from radio shack. The flux i used is marquette brand paste. Don't have any here with me since it is all work stuff.

One thing i would recommend is don't run your soldering iron too hot. I had it set at about halfway.

Have fun building.
