Posted: Wed Dec 17, 2008 8:53 am
Hello,
I have a project where I think your LK204-25-IY would work well, but I need to build a custom matrix keypad to fit my requirements. Do you have an example schematic for a standard matrix keypad?
Will it work if I literally just have an array of switches like this:

Or do I need some resistors in there?
Thanks!
