Has anyone had success in replacing the membrane keypad of an HMI? Specifically, I would like to repair several Mitsubishi E200, E1022, and Beijer Exter K20. A few years ago, I bought a couple of E1022 keypads on ebay. The quality was poor- it did not stick to the metal frame very well, and operation of several keys was intermittent. These were made in China, and nowadays there are lots of Chinese vendors hawking their wares on ebay. lso made there. Maybe quality has improved, but I'm hesitant to try again, unless someone can instill some confidence in me. Ideally, I'd like to find some leftover originals, but I think that's highly unlikely. Thanks!
