Conductive rubber button
Before explaining the details of the conductive rubber button, we will first focus on explaining exactly what the conductive rubber term means. Any rubber-like material that has conductive characteristics can serve as a conductive rubber button, and it is important that this material is able to remove electromagnetic interference (EMI). Electromagnetic interference (EMI) is a very common occurrence because electronics generally cause a certain type of noise, which we cannot hear and that noise creates electromagnetic interference (EMI). Construction and choice of material depends on several factors.
Industries where you may need a conductive rubber button are various. They are used for computing, health care and even aerospace, automotive and so on. In general, the conductive rubber button is used only for top quality electronics because it is necessary to pay attention to such details. In order to be able to give you accurate advice, it is necessary that you contact us and explain your needs.
In general, the electrical conductivity of rubber materials varies and some of the best are silicone, EPDM and neoprene. Nitriles are also often used. Each of these materials has a different application, but they are generally suitable for a conductive rubber button. The environment in which you will use the conductive rubber button also plays a role in the choice of materials, because some of the above materials are better able to withstand temperatures as high as silicone, and EPDM is flexible at low temperatures, weather resistance and so on. Buttons are generally similar in shape, but not all are identical, so according to your needs you can choose buttons that will be some other geometric shapes, not just a cube. The size is completely customizable to your needs, whether it is very large or very small buttons. We will also ask you if you need laser etching or silk-screen printing.
