Hello every body,I have an equipment which I am repairing it has special buttons (I attached the photo here),wen you push a button and you measure to see if the resistance is 0;some time you find some Kilo-ohms others you find infinite.
The circuits in use which is interfaced to a microcontroller is also attached;can you let me know how I can read those push buttons.
Thanks.
