A traditional membrane design may vary in size and complexity. Here a few different configurations:
- Membrane Keyboards

- Membrane Keypads
- Membrane Switch Panels
- Rubber Membrane Switch
- Membrane Switch Overlays
- Backlit Membrane Switches
- Metal Switch Keypad
- Stainless Steel Keyboards
- Touch Screen Membrane
- Membrane PCB
- Sealed Membrane Switches
The membrane switch was originally developed to meet the industry’s need for inexpensive custom switches with flexible and low profile characteristics. These switches today are being designed into companies’ products and used throughout all industries.
The electrical engineer would define a membrane switch as a momentary switch, with at least one contact in the ON position. Simple put, an electrical switch used for turning on and off a circuit.
A overlay is the top layer in a membrane switch design. The overlay presents the product’s graphics and together with other supporting layers is a membrane switch assembly.
Sigma 6 Electronics would be happy to send out an engineering sample.
