Do you know what the general parameters of membrane switches are?

Membrane switch is a switch made by printing technology. It has the advantages of being thin, sealed, and waterproof. It is widely used in various electronic devices. The following are some common parameters of membrane switches:

Physical parameters:

  1. size :

    • Overall dimensions (width, length, thickness)
    • Button size
    • spacing
  2. Material :

    • Panel material (usually polyester PET)
    • Backplane material (can be PET, PC, FR4, etc.)
  3. Number of layers :

    • Single, double or multi-layer structure
  4. Button Type :

    • Flat buttons
    • Convex buttons

Electrical parameters:

  1. Operating Voltage :

    • Typically 30V DC or less
  2. Working current :

    • Typically 100mA or less
  3. Contact resistance :

    • Typically 100Ω to 500Ω
  4. Insulation resistance :

    • Typically 100MΩ or higher
  5. Conductive mode :

    • Silver paste conductive
    • Carbon paste conductive

Mechanical parameters:

  1. Button life :

    • Typically more than 1,000,000 presses
  2. Operation intensity :

    • Typically 15g to 750g
  3. Rebound time :

    • Typically 6ms to 12ms
  4. Key travel :

    • Typically 0.1mm to 0.5mm

Environmental parameters:

  1. range of working temperature :

    • Typically -40°C to +70°C
  2. Storage temperature range :

    • Typically -40°C to +85°C
  3. Humidity range :

    • Relative humidity 40% to 90%
  4. Sealing performance :

    • Waterproof and dustproof rating (such as IP65)

Interface and features:

  1. Backlight :

    • LED backlight
    • EL backlight
  2. Connector Type :

    • FPC (Flexible Printed Circuit)
    • Rigid PCB
    • Lead wire (flat cable)
  3. Graphics and Logos :

    • Button Icon
    • Logo text
    • Printing Color
  4. Haptic Feedback :

    • Haptic feedback design
    • Tactile membrane

By selecting the appropriate parameters, membrane switches suitable for various application scenarios can be customized to meet the needs of different devices and environments. If you have specific application scenarios or parameter requirements, please provide more details so that I can provide more accurate suggestions.
