Rubber Keypads

Custom silicone rubberized keypads are an inexpensive and reliable interface solution for many applications. A rubber keypad offers design flexibility with a wide range of appearance, feel and function. Environmental sealing ribs, light pipes and other attributes can be incorporated into the keypad’s design. They can provide the tactile feedback and contact closure or be used in conjunction with metal or polyester domes.

Silicon Rubber Keypad Design Options

  1. Tactile, non-tactile
  2. Key profile, travel and force
  3. Backlit
  4. Environmentally sealed

Conductive Options

  • Molded conductive pill in carbon from 1.5mm to 10mm in diameter. Silver, gold and oval shapes are also available.
  • Printed conductive pills can be used for irregular shaped contacts, such as "ring" for LED backlighting in individual keys.


Screen printed

Painted and laser etched

Chemical and Wear Resistant Coatings

Silicone spray overcoat doubles the abrasion resistance of printed graphics.

Polyurethane spray coating increases abrasion resistance of graphics by 20X.

  • Clear epoxy deposition on key tops for a hard plastic feel or lens effect.
  • Parylene coating for resistance to most chemicals.
  • Silicone rubber keypads are among the most common features found in modern household electronics. They are considered to be an economical and highly reliable user interface solution, and can be used in almost all types of electronic and mechanical applications. There are several design options for rubberized silicone keypads, which attributes to the flexibility of the rubber material that is used.

How These Rubber Keypads Work?

Silicone rubber keypads work by creating momentary contact once a particular key or button is pressed. The contact is then disconnected when the pressure of the key or button is released. The key or button returns to its neutral position once the pressure is released.

A silicone rubber keypad is commonly found on remote controls and on control panels of various electronic household products such as television sets, audio and video products, electronic toys and as a user interface for numerous types of industrial equipment. Most of today's mobile phones and hand held remotes use silicone keypads as means to manipulate and access certain features of the device.

The markings of silicone keypads are used to identify the function of certain buttons or key. They are mainly printed, etched on the button or key of the device. Rubberized silicone keypads are very durable and are known to be resistant to certain chemicals. They have wear resistant coatings, which makes them more resistant to wear and tear.
