#113476 - No problems != No Bugs. Responding to: ???'s previous message |
Dear Erik,
Excellent point, I have, however, not had any problems. You are concluding no problems based on testing/Experience with device. But successful testing doesnt mean an end to problems. It only makes sure no known porblem exist. If the keys are working with dry contacts problems may arise at some time!!! This kind of problems even may not get reported since there is a tendency to press key again if it didnt work at first. Maybe, the fact that the silicon membrane keypads I use have a slight "scouring" action when pressed is the reason. I never expected these words from you how can you rely on something that maybe. If it is not designed properly to work with those uA contact currents it may fail!!! Having them running fine for some time doesnt necessarily mean design is perfect. Regards, Prahlad Purohit |
