Product Description
Custom Design Gold Plated Keys Standard Membrane Switch ROHS CE Certification
Construction
Layers: A standard membrane switch usually comprises five or more layers:
- Graphic Overlay: This top layer serves as the user interface, displaying operational instructions and is often printed on a hard-coated substrate like PET or polycarbonate.
- Spacer Top Adhesive: This layer adheres the graphic overlay to the rest of the switch.
- Dome Retainer: This layer holds the metal domes or shorting pads that activate the switch.
- Spacer Adhesive: This layer includes ventilation cuts to allow air flow when the switch is pressed.
- Circuit Layer: Conductive inks are printed on a flexible substrate to create the circuit. This layer is crucial for the switch's functionality.
- Mounting Adhesive: The bottom layer used to attach the switch to the desired application.
Materials: The layers are typically made from flexible materials such as polyester or polycarbonate, and the circuits are printed using conductive inks like silver or carbon.
Functionality
- Actuation: When a button on the membrane switch is pressed, the layers deform, allowing the conductive traces to make contact and complete the circuit. This action registers the keypress and can provide tactile feedback depending on the design [2].
Applications
Standard membrane switches are widely used in various devices, including:
- Microwave oven panels
- Air conditioner control panels
- TV remote controls
They are favored for their ease of cleaning, sealing capabilities, and low profile, making them suitable for a range of products.
Advantages
- Design Flexibility: They can be customized in various shapes and sizes, allowing for creative user interfaces.
- Cost-Effectiveness: Generally, standard membrane switches are more affordable compared to alternatives like PCB membrane switches, making them a popular choice for budget-conscious projects
