Button wiring.

Herk:

Hey,

     Here is the scenario:  If button 1=a and button 2=b, how do I wire button 3=ab.  I am using micro switches and only these three buttons can be used in this scenario.

Thanks,

Herk

Kevin Mullins:

So button 3= a+b ?

One side of your microswitch goes to ground/common as usual.

The other side goes to the action side of both button 1 and button 2.

Is that what you were asking?

Chris G:

Perhaps if you explained the scenario there could be an alternate solution...?

Herk:

Chris,

     I am modifying an x-arcade tankstick and have added a few buttons, one being an escape key.  The x-arcade circuit board has player2 + button4 = esc.  I want to have one button to be the escape key not the combo.


Kevin,

     I will try your solution right away but I think that makes all three buttons a+b.  Yup, all go a+b.  I need 1 to remain a only, 2 to remain b only and 3 to be a+b.

Thanks,

Herk

BobA:

2 diodes inserted in the action side would prevent a and b buttons from interactiing.  Not knowing the ciircuit it would be trial and error in positioning them properly as to polarity.   If it does not work one way it is the other way.
