Manufactures of custom silicone keypads design a wide variety of configurations and types of rubber keypads; they produce them for a wide assortment of applications and industries. Many of these manufacturers offer design and engineering assistance to ensure the keypads exceed the specification and expectation of their clients.
Silicone Rubber keypads are widely utilized in both industrial and consumer electronic products. This is largely because they provide a reliable and low-cost switching solution. Compression molding silicone properties are used by this technology. When the switch is depressed, the webbing deforms uniformly to generate a tactile response. Upon the removal of the pressure from the switch, the webbing goes back to its original position.
Capabilities
The capabilities include laser etching, all molding processes, custom finishes and in house graphics. They provide an effective economical quality resolution for the design requirements of each client. An outstanding choice is provided for even the most rigorous design specifications. Original molded processes enable windows and light pipes to be shaped as an essential component of the keypad throughout the manufacturing process. This makes them into just one sealed component.
Design
The design of rubber keypads can be done in such a way that they attain a positive tactile response when the keypad is depressed by the operator. To accomplish the favorable tactile feel intrinsic in this type of keypad, there should be an actuation force of 50 grams to 170 grams. In addition, it should have a minimum of .060″ of travel.
Alternatively, the manufacturer could incorporate a tactile layer in between the circuitry layer and the rubber keypad. This allows a good tactile feel even with minimal travel distances and small keys.
Advantages of Choosing Silicone Keypads
• Cost-effective
Silicone keypads are fairly economical on a per piece basis; however, they need relatively costly tooling. Typically, this makes them a design option for higher-volume projects.
• Outdoor Weatherability
These keypads have extraordinary resistance to aging and extreme temperatures. They also have outstanding resistant to moisture and chemicals.
• Back Lighting Flexibility
EL lighting, fiber optic lamps and LEDs can be used to backlight the keypads. The impact of the back lighting can be enhanced by laser-etching the keypad. The light pipes used in the individual keypads can be used to prevent light scatter and customize back lighting.
By itself, a silicone keypad is just that; it will not be able to function without other vital components. As such, it is important to use a manufacturer who specializes in integrating all the required components into intricate, feature-rich custom silicone keypads.
