Membrane switches are commonly used in electronic devices and control panels. These switches consist of a thin, flexible layer that contains touch-sensitive buttons or keys. To enhance their appearance and functionality, a matte oil coating can be applied to the membrane switch. In this article, we will explore the step-by-step process of putting matte oil on a membrane switch, ensuring a smooth and professional finish.

The Importance of Matte Oil Coating

Before diving into the steps, let’s understand why applying a matte oil coating to a membrane switch is essential. The matte oil coating provides several benefits:

  1. Enhanced Durability: The coating protects the membrane switch from wear and tear, extending its lifespan.
  2. Improved Appearance: Matte oil gives the switch a sleek and professional look, enhancing the overall aesthetic appeal.
  3. Anti-Glare Properties: The matte finish reduces glare, ensuring better visibility in various lighting conditions.
  4. Resistance to Smudges and Fingerprints: The coating minimizes the visibility of smudges and fingerprints, keeping the switch clean and neat.

Now, let’s explore the step-by-step process of putting matte oil on a membrane switch.

Steps of Putting Matte Oil on Membrane Switch

  1. Step 1: Gather the Materials
    • To begin, collect all the necessary materials: matte oil, a lint-free cloth, isopropyl alcohol, gloves, and a clean, dust-free workspace.
  2. Step 2: Prepare the Membrane Switch
    • Start by cleaning the membrane switch with isopropyl alcohol and a lint-free cloth. This step ensures that the surface is free from any dust, oil, or debris, providing a clean canvas for the matte oil application.
  3. Step 3: Shake the Matte Oil
    • Shake the matte oil container well to ensure the contents are thoroughly mixed. This step helps to maintain a consistent finish throughout the application process.
  4. Step 4: Apply Matte Oil
    • Put on gloves to protect your hands from direct contact with the matte oil. Apply a small amount of matte oil onto the lint-free cloth and gently rub it onto the surface of the membrane switch. Use even, circular motions to ensure uniform coverage.
  5. Step 5: Check for Imperfections
    • After applying the matte oil, inspect the membrane switch for any imperfections such as streaks or uneven coating. If you notice any, use a clean part of the cloth to gently buff and even out the coating.
  6. Step 6: Let it Dry
    • Allow the matte oil to dry completely. The drying time may vary depending on the type of matte oil used, so refer to the manufacturer’s instructions for specific guidelines.
  7. Step 7: Test the Switch
    • Once the coating is dry, test the membrane switch to ensure it functions properly. Press each button or key to confirm that the touch sensitivity is unaffected by the matte oil application.
  8. Step 8: Final Inspection
    • Take a final look at the membrane switch to ensure the matte oil coating is smooth, evenly applied, and free from any visible imperfections.

Frequently Asked Questions (FAQs)

  1. Q: Can I use any type of matte oil for coating the membrane switch?
    • A: It is recommended to use matte oil specifically designed for electronics and switches. These formulations are designed to provide optimal protection and adhesion.
  2. Q: Can I apply matte oil on a membrane switch with a graphic overlay?
    • A: Yes, you can apply matte oil to a membrane switch with a graphic overlay. However, exercise caution to prevent any damage to the graphic design during the application process.
  3. Q: How often should I reapply the matte oil coating?
    • A: The frequency of reapplication depends on the usage and environmental conditions. In general, it is advisable to reapply the coating every six months to a year for optimal protection and appearance.
  4. Q: Can I use a different type of cloth for applying the matte oil?
    • A: It is recommended to use a lint-free cloth to avoid leaving fibers or lint on the membrane switch. Microfiber cloths are a popular choice for this purpose.
  5. Q: Can I remove the matte oil coating if I want to revert to the original surface?
    • A: Yes, the matte oil coating can be removed using isopropyl alcohol and a lint-free cloth. However, it is crucial to follow the manufacturer’s instructions and exercise caution to avoid damaging the membrane switch.
  6. Q: Can I apply additional layers of matte oil for a more pronounced matte effect?
    • A: While it is possible to apply additional layers of matte oil, it is essential to consider the switch’s touch sensitivity. Applying too many layers may affect the switch’s functionality, so it is recommended to test the touch sensitivity after each layer.


Applying a matte oil coating to a membrane switch is a straightforward process that can significantly enhance its durability and appearance. By following the step-by-step instructions outlined in this article, you can achieve a professional and sleek matte finish. Remember to gather all the necessary materials, prepare the switch, apply the matte oil evenly, and inspect the final result. With proper care and maintenance, your membrane switch will not only look impressive but also stand the test of time.
