Silicon Rubber Keypads

A rubber keypad membrane switch uses compression-molded silicone rubber with conductive carbon pills or with non-conductive rubber actuators. The compression molding process creates an angled web around a keypad center. When a keypad is pressed, the webbing collapses or deforms to produce a tactile response. When the pressure on the keypad is released, the webbing returns the keypad to its original position with positive feedback. The closure of the switch circuit occurs when the conductive pill or printed conductive ink makes contact to a PCB when the web has been deformed.
Benefits of Using Rubber Keypads:
● Cost-effective
● Outdoor Weatherability
● Design Flexibility
  o Superior tactile feedback. Can utilize carbon pills, non-conductive rubber actuators, or stainless steel tactile domes.
  o Unusual keypad shapes and sizes can be used, as well as different rubber durometers (hardness).
  o Multiple colors can be achieved by flow molding the color into the compression molding process.
  o Rubber keypad graphics can be further customized by screen printing the keypad top surface.
  o Rubber keypad switches can be spray coated with polyurethane for enhanced durability.
  o Rubber keypads can be impervious to liquids, dust and gases by utilizing creative designs such as a wrap-around design.
● Back Lighting Flexibility
