Silicone keypads play a critical role in avionics control panels, ensuring smooth and precise operation in aircraft. However, these keypads are exposed to harsh environmental conditions, which can lead to wear and tear over time. To maintain the longevity and durability of silicone keypads in avionics control panels, it’s essential to implement proper care and maintenance practices. In this article, we will explore strategies to enhance the durability and lifespan of silicone keypads, ensuring optimal performance in aviation applications.

Understanding Silicone Keypads

Before delving into maintenance techniques, let’s first understand what silicone keypads are and their significance in avionics control panels.

What Are Silicone Keypads?

Silicone keypads are interface components made from silicone rubber. They feature tactile buttons and are designed for various applications, including aviation. These keypads are known for their durability, resistance to environmental factors, and excellent tactile feedback.

Maintenance and Care Tips for Silicone Keypads

Maintaining silicone keypads is crucial to ensure their long-term functionality. Here are some essential maintenance and care tips:

1. Regular Cleaning

Regularly clean silicone keypads with a mild detergent and a soft, lint-free cloth. Avoid abrasive materials or harsh chemicals that can damage the silicone surface.

2. Protect from Extreme Temperatures

Silicone keypads can withstand a wide temperature range, but extreme heat or cold can affect their performance. Store avionics control panels in a climate-controlled environment when not in use.

3. Moisture Protection

Silicone keypads are resistant to moisture, but prolonged exposure to water can lead to deterioration. Ensure that control panels are sealed properly to prevent moisture ingress.

4. Avoid Sharp Objects

Prevent sharp objects or tools from coming into contact with silicone keypads, as they can cause punctures or tears.

5. Lubrication

Apply silicone-based lubricants sparingly to maintain button responsiveness. Consult the manufacturer’s guidelines for suitable lubricants.

6. Regular Inspection

Periodically inspect silicone keypads for signs of wear, tear, or damage. Replace any damaged keypads promptly to avoid operational issues.

Advantages of Well-Maintained Silicone Keypads

Proper maintenance of silicone keypads offers several advantages in avionics control panels:

Enhanced Longevity

Regular care and maintenance can significantly extend the lifespan of silicone keypads, reducing replacement costs.

Reliable Performance

Well-maintained keypads ensure reliable and precise operation of avionics systems, contributing to the safety of flights.

Cost Savings

By preventing premature keypad failures, you can avoid costly repairs or replacements.

Improved User Experience

Maintaining tactile feedback and button responsiveness enhances the overall user experience in avionics control.


In conclusion, silicone keypads are essential components of avionics control panels, and their durability and lifespan can be significantly enhanced through proper care and maintenance. Regular cleaning, protection from extreme conditions, moisture prevention, and routine inspection are key practices to ensure the optimal performance of these keypads. By following these guidelines, you can enjoy reliable avionics control and cost savings in the long run.


  1. How often should I clean silicone keypads? Regular cleaning is recommended, at least once every few months, or more frequently if needed.
  2. Can I use any lubricant for silicone keypads? It’s best to use silicone-based lubricants specifically designed for rubber components.
  3. What should I do if I notice signs of wear on silicone keypads? Replace damaged keypads as soon as possible to prevent operational issues.
  4. Are silicone keypads suitable for extreme temperature environments? Silicone keypads can withstand a wide temperature range, but extreme conditions should be avoided.
  5. Can I repair a damaged silicone keypad, or should I replace it? It’s often more cost-effective to replace damaged keypads rather than attempting repairs.
