Rubber Keypad Membrane Switches

Rubber Keypad Membrane Switches = Silicone Rubber Keypad Overlay+ Membrane Circuit

Rubber keypad Membrane Switches are an excellent choice for device operation controls. It is soft and elastic. It can give users a very nice touch feeling. In addition, silicone rubber also has the following features and benefits:

  • Excellent resistance to both heat and low temperature (-55℃ to 250℃)
  • Minimum noise generation due to soft and elastic contact structure
  • Minimum abrasion and high resistance to SO2 and oxidation even in heavy humidity
  • Water and contamination resistant

Cosmetically appealing, 3-D Silicone Rubber Keypad offers the reliability of a vivid 3d membrane shapes or strong unevent result , with the three-dimensional look and tactile feel of a silicone rubber keypad for a variety of applications including medical, industrial, and commercial products.

This type of membrane switch is consisted of silicone rubber top operation panel and the lower layer PCB assembly together. Its top overlay is flexiable, panel shape and buttons shapes, printing and engraving pattern, screen printing everly customized available. Therefore, its lower circuit part, that is PCB assembly, which depends on funcationality of the silicone rubber keypad membrane switch completely. People often like the nice feeling and soft and comfortable experience from silicone rubber keypad when they operate these keypads. So silicone rubber keypad membrane switches can be utilized in many fields in our daily life.

Why need rubber keypad membrane switches? Compare to PET keypad membrane switch

As we know the common membrane switch is usually made from PET and PC film as the graphic overlay. Such product can be thin, usually a few milimeters in total. But sometimes many customers design their products to add silicone rubber keypad. Because of silicone rubber can give users a very good touch feeling. In addition, silicone rubber keypads can carry with carbon pills on the backside of the buttons, the carbon pills are conductive, and they can be combined with membrane circuit very easily. We only need to put silicone rubber keypad on the membrane circuit layer, then assemble with PCB together. When you press the buttons, the carbon pills will connect to the gold pads, then trigger the function.

The silicone rubber keypad membrane switches also can achieve backlighting easily. Justly we know that the silicone rubber raw material is usually translucent. It is light through. After painting we wanted colors on the silicone rubber. We need to laser to etch the backlit symbols and letters, then the LED light on the PCB or membrane circuit can be through the etched area out to get the backlit effect.

Silicone Rubber is easy to clean, once the keypad is contaminated. The silicone rubber keypad’s press life also is very long. At least 1, 000, 000 times above. It is very durable and not easily damaged. So rubber keypad switches are widely used in machinery, industrial manufacturing, vending machines, dirty and oil contaminated environment, and others.
