Silicone Rubber Keypads / Elastomeric Keypad / Elastomer Keyboards

Silicone rubber keypads are the most widely used form of switch technology today. We offer reliability, long life and design flexibility. Conductive rubber switches and keypads were originally developed for the electronics industry to meet the increasing demand for inexpensive momentary switches. Conductive rubber keypads are desirable due they look and feel like traditional push-button style switches. But do not have their inherent disadvantages.

Since their introduction over 30 years ago, conductive rubber switches and keypads have gained enormous popularity and wide-range acceptance because of their reliability, long operational life and excellent tactile feel.

Innovative key coatings for our silicone rubber keypads are silicone, parylene, and Dura (Hard Coat). Silicone rubber keypads can be designed for applications exposed to water and hydrocarbons. Enhanced graphics and lighting options allow your product to incorporate features not found on standard silicone.

Silicone Rubber Benefits:

Silicone rubber is an excellent choice for device operation controls. Beelow are its characteristics:

  • 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
  • Design both tactile and linear feedback
  • Translucent materials available
  • Cost effective
  • Multi-color designs easily accommodated
  • Water and contamination resistant

Main Technique Parameters:

Tensile Strength (kg/cm²) ≥70
Tear Strength (kg/cm) >12
Insulations Resistance ≥100Mohm at250V DC
Contact Resistance ≤200ohm at 12V DC
