Multi-function joystick buttons without relays

yes, use an AND gate or a "diode and"

I'm not sure I follow how you'd accomplish this with logic gates. Would you mind explaining how you would go about wiring this?

I want to effectively create another set of buttons - AX BX CX DX EX - by wiring up five additional momentary switches. When the AX button is pressed, it not only pulls A to ground but also X. Thus, the joystick controller simply sees this as simultaneous pressing of A and X.

It's also known as the diode-or:

In the first circuit shown, the +5VA, B, and C each have a pullup R (4.7k-22k) to the +5v., and the button to ground is to the left of each diode. The one they have labeled "TERMPOWER OUT" is your "X".

Have Fun! Rich

The banded end of each diode is at the bottom.

I thought you wanted something slightly different.

UPPERCASE = outputs lowercase = inputs (low when pressed)

A = a ? ax B = b ? bx C = c ? cx D = d ? dx E = e ? ex X = ax ? bx ? cx ? dx ? ex (I used an uncommon symbols if it doesn't show correctly '?' is 'and')
