Hi Everyone,
I am making my very first project using PCB contacts for a rubber keypad and was wondering if there are any debouncing considerations that need to be met.
Typically for a mechanical NO switch I have used the RC method which works great for those switches.
Does something similar need to be done for PCB contacts? I would think that the rubber keypad and PCB contact would not have the debouncing issues like we see in mechanical switches but since I have no prior experience in working with these I wanted to double check.
The layout will be in a matrix form very similar to this schematic:

Thanks in advance for the help!
