PCB Membrane Switch Panel

• Waterproof, dustproof, and oil resistant: PCB film switches can effectively prevent the intrusion of moisture, dust, and grease, ensuring long-term stable use

• Long lifespan: Due to the use of high-quality materials and processes, the service life of PCB film switches can usually reach more than three years, and can even withstand up to one million button operations

• Good sealing: By using different materials and technologies, the membrane switch can be made waterproof, oil resistant, pollution resistant, anti-static, and resistant to high and low temperatures

• Low cost: Compared to other types of switches, PCB film switches have lower manufacturing costs and are suitable for large-scale production and application

  
  

1. By tactile feedback: Can be categorised into flat non-tactile type, film convex tactile type, raised bezel non-tactile type, raised bezel tactile type, embossed panel tactile type, and metal dome type.

2. By illumination function: Can be categorised into standard type and illuminated type. Illuminated membrane switch panels require a bottom mould to be opened, with LED circuits capable of being integrated onto the same layer or a different layer as the underlying circuitry.

• Standard indoor environments (e.g., household appliances, office equipment): Standard polyester (PET) or polycarbonate (PC) panels suffice, with an IP40 protection rating.

• Damp/greasy environments (e.g., kitchen appliances, industrial washers): High-seal structures are mandatory. Prioritise oil-resistant PC panels, with an IP65 or higher protection rating to prevent liquid ingress into circuitry.

• Outdoor/high-temperature environments (e.g., vehicle-mounted equipment, outdoor detectors): Panels must possess UV resistance and high-temperature tolerance. PET with anti-UV coating may be selected, whilst circuit layers must withstand temperatures from -40°C to 85°C or higher to prevent thermal failure.

• Medical settings (e.g., patient monitors, infusion pumps): Panel materials must comply with medical-grade standards (e.g., FDA certification), withstand alcohol-based disinfection wipes, and utilise non-toxic, non-volatile printing inks. Antimicrobial properties are advantageous.
