Have you ever noticed the several components that make up your cell phone? How can you press the digits so easily? How is it that pressing a few buttons makes so many things happen? The secret lies in the use of Membrane Switches. Technically speaking, the Membrane switch is a machine-human interface that makes it possible for a user to communicate his commands to the machine.
Architecture Of A Membrane Switch
In a typical Membrane Switch, there are basically four layers, which are as follows -
- Graphic Overlay
- Circuit Spacer
- Printed Circuit Layer
- Bottom Adhesive
Of these the Graphic Overlay acts as a graphic interface between the users & the machine. It is essential to ensure that proper material is selected for making the overlay so as to enhance the aesthetic appeal of the product as well as to ensure that it has an extended life. The commonly used materials for making overlays include polycarbonate & polyester. Both materials have their own advantages & final selection depends on the buyer. Embossing can also be done over the graphic overlays to make them more attractive.
Apart from the graphic overlay, another important part of the Membrane Switch is the printed circuit layer. In a typical membrane switch, the circuit layer is usually made of polyester printed with silver conductive ink.
Categorization Of A Membrane Switch
Membrane Switches are of two types - a Membrane Switch with a tactile feedback and Membrane Switch with a non-tactile feedback. Tactile Membrane Switches provide instant feedback to the users. Stainless Steel or polyester Domes are incorporated in the design to ensure that the users get a tactile feedback every time the Membrane Switch is pressed.
On the other hand, there are Non-Tactile Membrane Switches in which the users do not get any type of feedback from the machine. But these Non-Tactile Membrane Switches are very economical & reliable.
