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 became desirable
because 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. It possesses the following 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;
In addition, silicone rubber offers several features that make its design and usage flexible;
• Design both tactile and linear feedback;
• Translucent materials available ;
• Cost effective;
• Multi-color designs easily accommodated;
• Water and contamination resistant ;
Cosmetically appealing, 3-D Rubber Keypads offer the reliability of a membrane or PCB-substrate switch, with the three dimensional look and tactile feel of a silicone rubber keypad for a variety of applications including medical, industrial and commercial products.
