The Interface Between Human and Machine…


Difficult projects that can be made reality with screen and digital printed membrane switches are virtually limitless. Varieties of textures and flexibility are the strong suit of membrane switches and can be easily tailored to the specifics of your project.

PPS membrane switches use only the highest quality parts and materials. In many cases / projects our standards of material exceed the bid request.

What are Membrane Switches?

Membrane Switches are printed electronic circuits that require finger pressure to open and close the circuit. Conductive Inks are used and are screen printed on to the desired base using: Graphite, Silver or sometimes carbon.

User interfaces are a broad set of terms for Membrane Switches that act as a touch point for actuating the switch. toggle, button or slide. Safety is a large factor as ergonomic positioning of the operator can be “sighted in” with proper design of the human interface part of the machinery, instrument or piece of equipment.

How to build a Membrane Switch

Thin layers of many different materials can be used in construction of a membrane switch as well as many types of adhesive. 4 to 9 layers can be used creating a membrane switch.

The artistic layer is the top most overlay which generally will include graphics and artistic detail which can also include an Antimicrobial Coating. The underlying layers known as substrate, can include: Polyester, Polycarbonate, Hard Coat Polyester, Hard Coat Polycarbonate and/or Acrylic. LED’s are sometimes used to back light or to direct behavior by pointing or warning the operator towards or away from particular actions. Clickable Domes can be included in other layers depending on the type of functionality desired. The bottom layer can be backed with adhesive for lifetime fit and function.

Where are Membranes Switches used?

All industries demand Membrane Switches as the switches can be designed for a variety of environments with form and function built in.
