What is the difference between a foil contact keyboard and metal contact keyboard?
Mkz
There are two technologies in the way the keys of a keyboard make contact: foil contact and metal contact. The foil contact keyboard has two layers of foil that when you press a key makes a contact and close a circuit. When it's released a small spring under keycap raises the key. The metal contact keyboard uses two metal plates to make contact, and again a spring under keycap raises the key when it's released. Metal contact keyboards give the keystroke clear and definitive contact.
