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.Molded conductive pill in carbon from 1.5mm to 10mm in diameter. Silver, gold and oval shapes are also available.
|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 function by creating momentary contact when a key or button is pressed, with disconnection upon release. They are commonly used in remote controls, household electronic devices, industrial equipment interfaces, and mobile phones. Markings on these keypads indicate button functions and are typically printed or etched. Silicone keypads are highly durable, resistant to chemicals, and equipped with wear-resistant coatings, enhancing their longevity.
