Today's keyboards are actually plastic keys with a mylar sheet inbetween the keys and rubber membrane. This sets up a static charge that is recognized by the computer;s motherboard. The process to see and save the letter follows the same procedure outlined above.
In both cases, the keyboard is classified as an "output peripheral mechanical device". The difference between the two devices is that rubber membrane and mylar sheet. If any liquid (like hot coffee or tea) were poured over the keys on the top keyboard, the keyboard was permanently damaged. In the keyboard with the rubber membrane, the screws could be removed from the bottom of the keyboard, the mylar and rubber carefully taken out then wiped dry and cleaned.
There were more moving parts to the older keyboard so they were more expensive. Since there are virtually no moving parts to today's keyboard, they are cheap to replace. If damage is done to either keyboard, you can clean it out. If a part is broken, however, simply buy a new one. I hope this answers your question.
