KeyWiz: Wiring Shazam button.

[Generic Eric]

I tried to read the FAQ for wiring the Shazam button on the KeyWhiz but didn't find the answer I was looking for.  Do I need diodes for when I wire the Shazam button?  If so, which ones? Thanks

The Shazaaam! button is wired like any other.  The only time diodes are necessary is if you want to dedicate a button to Shazaaamed key output.

Where the diodes come into play is if you want to wire more buttons than the key-wiz has inputs.
It's possible to make a matrix where pressing a single button will trigger both the shazaam key and one of the other keys, therefore posting the alternate key output.  Since multiple buttons are connected to the same inputs, the diodes are required to keep the signal from backtracking through the wiring and screwing up the other input.  (they are like one way streets)

If all you want to do is use it as a shift function, wire it like any other button like Randy said.
Do that, hold the shazaam button and another button and you get the alternate key output.

I could have posted my CP earlier.



The orange button in the top middle will be my Shazam button.
