2.Basic Knowledge
What is a "Membrane Switch"?
A membrane switch is a printed electronic circuit that uses pressure to open and close a circuit. The membrane switch circuitry is most often screen printed using conductive inks, which are typically made of silver, carbon, and/or graphite.
Membrane switches are part of a range of devices considered to be user interfaces (also called operator interfaces, or man-machine interfaces) along with display-based touch screens, and mechanical switches such as push-button, toggle, rocker, and slide switches. The ultimate purpose of a membrane switch is to serve as the interface between man and machine, enabling an operator to communicate with a piece of equipment, instrument, or machinery.

Features & benefits of membrane switches include:
Completely sealed surface - easily cleaned and sterilized.
Low Profile - no crevices that can trap contaminants.
A cost-effective alternative - less costly than rubber keypad assemblies and capacitive touch keypads.
Thin profile - saves valuable space in your product design.
Easy to interface with existing controllers - no special electronics required, as with touch screens.
Versatile graphic interface - overlays can be screen or digitally printed with stunning, photo-quality
graphic effects.
Protection by design - Easier to protect from UV radiation than rubber keypads.
Water-resistant designs - meets NEMA 4 and IP 67 specifications.

How Are Membrane Switches Constructed?
Membrane switches are essentially a sandwich of thin layers that are bonded together using pressure sensitive adhesives. Depending on the application requirements, a membrane switch will consist of as few as 4, and as many as 9 layers. In contrast to mechanical switches, membrane switches offer the advantage of lower cost, they consume less design space with their low profile, are easy to clean, and they offer a sleeker, ergonomic, and aesthetically pleasing appearance.
 
The visible top layer of a membrane switch is the graphic overlay, with printed circuitry underneath the overlay. The circuitry can also incorporate different layers such as polyester (silver flex), polyimide (copper flex), and rigid PCB layers. Activation of a switch occurs when a printed shorting pad or metal dome makes contact with the bottom circuit layer thus, closing the circuit.
 

What Industries Use Membrane Switches?
Membrane switches can be found in a variety of different industries. Medical instrumentation and laboratory equipment are ideal markets for membrane switches. These switches can be designed to be sealed from moisture and contaminants and with anti-microbial coatings to resist bacterial growth and harsh chemicals. Membrane switches are also utilized in industries such as electronic test and telecommunication networking equipment. Industrial controls and fitness equipment are also industries where membrane switches are the user interface of choice.
