Project : Using a Touch Key Self-locking Switch Module with Exxos RAM Kit
Posted: Sat Oct 26, 2019 1:54 pm
Hello,
I bought this little module in China at sunsky-online.com : A007 Touch Key Key Self-locking Switch Module (~3$ each) .
As I don't like to drill holes in my Atari cases, I would like to use this module as a switch to switch from 1MB to 4MB and ideally place it under the keyboard instead of the existing LED or outside with a simple double-sided scotch.
I found a video on youtube that shows how it works.
That's how mine looks like: Obviously there is no documentation at all. So I tested the continuity and voltage between the PINs.
It gives this with the PSU negative 5V connected to GND and the positive connected to VDD:
The question is: Is it possible to use this switch to select 1M or 4M without frying exxos RAM module ? Because i really don't know how to do
