Product Description
High-Performance ESD Shielding Membrane Switch With Flat Keys For Rear Surface Printing Customizable And Durable
A high-performance ESD shielding membrane switch with flat keys, designed for rear surface printing, customizable, and durable, incorporates several key features:
- ESD Shielding: This protects the switch's circuitry from electrostatic discharge (ESD), which can damage sensitive electronic components [1][2]. Common methods include:
- Printed Shield: Using carbon or silver ink printed over the circuit [3]. A grid pattern is often used to reduce cost [3].
- Aluminum Foil: A more conductive but expensive option, adding an extra layer to the switch [1][3].
- Conductive Laminates, Tapes, and Foils: Providing a higher level of dissipative properties [1].
- ITO Coated Polyester: A transparent, conductive material for clear window areas [1][3].
- Copper Mesh Fabric: A high-quality, but more expensive option, often used in military and communication units, that also protects against EMI and RFI [1].
- Flat Keys: These provide a low profile and are often preferred for their aesthetic and ease of cleaning [4].
- Rear Surface Printing: This protects the graphics from damage and wear, as the printing is on the underside of the overlay material [5].
- Customization: Membrane switches are highly customizable in terms of size, number of keys, materials, and printing [6][7].
- Durability: Constructed from materials like polyester and polycarbonate, membrane switches are known for their flexibility and dielectric strength [6]. They can have a long lifecycle, sometimes exceeding 1,000,000 actuations [6].
- Materials: Common materials include polyester (PET) and polycarbonate (PC) for the overlay [6][8].
- Layers: Typically composed of multiple layers (4-8), including a graphic overlay, adhesive layers, and circuit layers [6].
- Printing: Utilizes technologies like silkscreen and digital printing for creating graphics and circuitry [6].
- Applications: Used across various industries, including medical devices, home appliances, automotive, and military equipment [2][6].
- Shielding against EMI/RFI: Besides ESD, membrane switches can be shielded against electromagnetic interference (EMI) and radio frequency interference (RFI) [1][9].
