Membrane switch keyboards

Membrane Keyboards & Membrane Keypads 


A membrane keyboard is a computer keyboard whose keys are not separate moving parts as with a

majority of other keyboards, but rather are pressure pads that are printed on a flat flexible surface.

Today, smaller versions of membrane keyboards have been used for PDA\'s, handheld calculators,

remote controls and microwave ovens. 

When a user presses a simulated key, the top membrane is pushed through the spacer hole and

makes contact with the bottom membrane, completing the circuit. Membrane keyboards, which are

much hardier than normal key switch keyboards, offer the advantage of complete customization by

programming the cell matrix for any application.

Most computer keyboards today use the technology in the definition above, but with molded key

capsrather than printed keys. As a result, they are not as hazard proof, but the economical

membrane construction enables the keyboard to retail at lower cost.
