What is a Membrane Switch?

A membrane switch is an interface between man and machine, enabling an operator to communicate with equipment, instrumentation, or machinery. 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 or carbon. Membrane switches are part of a range of devices considered to be user interfaces or human machine interfaces (HMIs) along with touch screens and mechanical switches. Read more..

Parking Meter Problem Solved!

A customer recently contacted CSI Keyboards to help them design and manufacture a new custom keypad for outdoor use. The application was a parking meter that was currently using a non-tactile capacitive switch using molded polycarbonate. The customer’s end goal was to create a keypad that had raised profile and tactile feedback with each button press, while maintaining a waterproof seal against the weather’s elements. Read more..

Need a Backlit Environmentally Sealed Switch?

CSI Keyboards was asked by our customer to design a backlit membrane keypad assembly that would withstand
the destructive temperatures of the arctic as well as the dry heat of the desert without these extremes
degrading its functionality. The reliability of these switches was paramount as they were to be used
as lighting controls for temporary military field housing. Read more..

What is the Difference Between Mechanical Switches vs. Membrane Keypads?

A common question raised by many of our customers is: what is the difference between a mechanical switch and a membrane keypad? Keypads can typically be broken down into one of two different categories: membrane keypads and mechanical switches. While their primary purpose as a user interface is the same, they are actually completely different solutions. Read more..
