Keyboard Dictionary

Definition for "Membrane"

Technologies

A membrane is a form of circuitry known for its use in several keyboard switch designs. It takes the form of several plastic sheets filled with traces that have contact points designed to be pushed together to complete a circuit. On their own, membranes are incapable of providing any meaningful auditory and/or tactile feedback. Thus, a common and economical pairing for membranes is rubber domes to provide a tactile response. However, more complex mechanisms can also be used with membranes such as the Model M's buckling springs.
