DIY Matrix Keypad

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!

Jup the schema you have should work, no resistors needed.
