Main classifications of membrane switches:

Metal membrane switches: These switches use contact materials such as gold, silver, and copper, featuring high reliability, durability, and excellent tactile feedback. They are widely used in various electronic devices.

Flexible thin-film switches: These switches use contact materials such as polyimide, polyester, and polyimide + silver, offering advantages such as easy assembly, freeform design, and soft tactile feedback. They are widely used in computers, electronic devices, toys, and other applications.

Rigid thin-film switches: These switches use contact materials such as copper and stainless steel, offering advantages such as easy material sourcing, stable manufacturing processes, and low resistance. They are widely used in various electronic devices.

Explosion-proof thin-film switches: These switches are designed to operate in flammable and explosive environments, offering features such as safety, reliability, and high-temperature resistance. They are widely used in industries such as petroleum and chemicals.

Waterproof membrane switches: These switches have waterproof functionality and can operate in underwater environments, making them widely used in diving equipment, underwater robots, and other applications.

Other types of membrane switches: Such as multi-layer membrane switches, temperature-sensing membrane switches, light-sensitive membrane switches, and pressure-sensing membrane switches, which are widely used in various special-purpose electronic devices.
