A4tek manufactures switches that are very comparable to the ones I've been using for quite some time now. On the previous keyboard, they had no failures in the previous four years. Particular care was taken with the red switches (which do not click). If you don't press down very hard, the sound will be slightly louder than the membrane, which is the plastic of the keycap rubbing up against the plastic of the switch base. In the subsequent generation, each and every one of the flaws that I have outlined will be fixed. I tested them both, and although the current model is somewhat more comfortable to wear, they do not sell quiet switches to us.
