Convex Membrane Switches
Convex membrane switches from LEESUN offer tactile feedback, durable construction, and customizable designs. They are suitable for control panels, appliances, and industrial devices.
High-Quality Tactile Membrane Switches
Convex membrane switches consist of two main parts: PC (polycarbonate) and PET (polyethylene terephthalate) plates. These plates work together to create strong and lasting buttons. The PC plate gives the button its shape and support, while the PET plate forms the touch surface, ensuring stability and reliability.
LEESUN’s convex membrane switches provide easy and dependable control for modern devices. They are designed with tough PC and PET layers and can be fitted with metal or Mylar domes. This adds responsive tactile feedback when you press the buttons, making them feel more precise. The switches are slim, sealed, and sturdy. Therefore, they are perfect for electronics, appliance panels, medical devices, and industrial controls.
For applications requiring electrostatic protection, ESD Drain (Electrostatic Discharge dissipation) can be integrated into the membrane switch design. This helps safely discharge static electricity away from sensitive electronic components, reducing the risk of malfunction or damage in environments where static buildup is a concern.
We offer both resistive membrane switches and capacitive membrane switches. Our convex membrane switches can be customized and work well with backlighting. Furthermore, they last a long time and offer great value for companies. These switches meet the needs for easy-to-use and elegant designs that perform well.
