发明名称 Keyboard switch
摘要 A keyboard switch has a deformable membrane which, when deformed, enables electrical contact between a pair of contacts. A key stem is urged away from the deformable membrane by an elastic body. When the key stem is displaced sufficiently, the elastic body imparts a click feel. The key stem, when displaced a sufficient amount, deforms the deformable membrane to make the electrical contact.
