Membrane Key Switch Introduction

A kind of keyboard switch mechanism found in many human-machine interface systems, especially control keyboards, is referred to as a “Membrane Key Switch”. It is a substitute for key switches that are mechanical. The keys in a membrane key switch are a continuous, flexible membrane sheet rather than separate, movable pieces.

The operation of membrane key switches can be summarized as follows:

  • Membrane Layer: Aslo named “graphic overlay“, is a flexible, flat membrane film. Typically, this layer has printed artwork and patten on the surface.
  • Circuit Formation: A certain region on the membrane correlates to each key on the keyboard. The spacer compresses as a result of the top membrane layer being forced downward when a key is pressed. By doing this, an electrical circuit is completed by matching the spacer’s holes with particular contact sites on the bottom membrane layer.
  • Electrical Signal: When the circuit is complete, an electrical signal is produced that tells the keyboard’s controller which key has been hit.
  • Tactile Feedback: A few membrane keyboards have tiny embossed domes covering the contact locations that are called tactile domes. When a key is pressed, these domes give the user a tactile feedback that confirms what they just felt.
