Hello,

Thinking of making a 737 FMC PCB for MF with built in socket for a MEGA. I don't have a spare MEGA or buttons to check the wiring.

Please can you advise if the wiring in this example schematic is correct for multiple 6x6 tactile button/switch?

Or does MEGA pin have to go #4 on each tactile?

Thanks.

Thanks Stephan.

I had it wired so each MEGA pin went to #4 of each tactile button. But, I was advised it should actually be #3 (so you have both wires on the left).

Tricky to check without the hardware, but I will make the changes needed. Hoping to show it here soon.

Thanks.

Hi
You need to check the "Datasheet" of the switches.

As i know some bototns have the switch between the upper and the lower ports..... Other have the switch between the left and the right ports.

To get sure before you order the PCB i would make a testrun on a breadboard or check with Multimeter.... Or if you got check the datasheet.
Good Luck !
