Do plum and topre have individual switches for each key, or is the mechanism dependent on the pcb? I'm just wondering, so if a switch fails can you replace the one switch or is the whole thing done for?

The mechanism has a conical spring under the rubber, which gets recognized by the the motherboard at a certain distance. I suppose if the motherboards detection failed you'd be sol, but the likelihood of that is pretty low. Edit: I'm not even sure if it's possible for that detection to fail outside of the spring or rubber

ApplecheeksWell the switches will fail eventually. With an mx switch you can replace an individual switch. I guess with this, when it begins to fail, the whole board is gone.

When an MX switch fails though it's because it's a mechanical switch, but these aren't mechanical, they don't have that problem. The rubber would wear out before anything, and even those are usually rated at what, 90 million? And the replacement sheets are dirt cheap and readily available.

ApplecheeksI get that they're not mechanical, and I get that they're rated at a long lifespan, yadda yadda... But the point still is that when one capacitive sensor fails, the whole pcb is useless. If I can't remove and replace an individual failed switch, then what's the point?

All i was trying to say was after all my looking, all I've ever heard people say about their EC boards are that the rubber gets bad, but I haven't seen a thing about the pcbs failing on them. But yes, in the event that that somehow occurred, you'd need to get a new one.
