There are many different types of Membrane Switch on the market, and they will be used in different scenarios due to different designs. Today we would like to introduce the Polydome Membrane Switch to you. One of its important features is that the Polydome Design has no Metal Dome under the line, so this type of membrane Switch is also called Polydome Membrane Switch or PET switch or Polydome Switch.

What is the definition of Polydome Membrane Switch?

Polydome Membrane Switch generally prints silver dots on the fixed layer of the structure or the back of the top layer and embossed polyester. This is generally referred to as the top-level line in the structure. Or not only the silver dots but also the lines are printed under the fixed layer. In terms of the shape design and size of the Polydome of the Polydome Membrane Switch, there are more shapes to choose from, and the shape design and size will have different effects on the Tactile Feedback. It will also have a different impact on lifespan.

What are the advantages of Polydome Membrane switch?

1. It can be driven without a large load.

2. The cost is relatively lower, and the sensitivity is not bad. But the mold cost is relatively high.

3. Because of getting rid of the limitation of Metal Dome and combining the characteristics of polyester material, the product has the opportunity to reach millions of times without loss of function.

4. Easy to clean and durable while removing Metal Dome. Membrane switches of the Metal Dome type undergo Metal Dome deflection with use.

5. A denser keyboard input profile.

6. Less noise
