A membrane switch or flat switch consists of a printed polyester or polycarbonate overlay that adheres to a printed circuit, using pressure to open and close the circuit. A membrane switch is considered a "momentary action" switch, meaning that the switch is essentially always on, but when the switch is pressed, the circuit is temporarily closed, activating the key function. The switch is a critical aspect of the end product as it is the interface between the user and the machine, enabling the operator to communicate with the equipment, instrument or machinery. The membrane switch circuit is screen printed using conductive inks that are typically made of silver or carbon. Membrane switches are part of a range of devices that are considered user interfaces or human machine interfaces.

Features of IP67 medical equipment membrane switch:
Dust and Water Resistance: The IP67 standard indicates that the switch is completely dustproof, meaning no dust can enter the switch interior. Additionally, the switch can be submerged in water up to 1 meter deep for 30 minutes without water ingress.
This design enables the membrane switch to withstand dust and water intrusion in medical environments, ensuring stable operation and safety of the equipment.
Material Properties: PC film is a polycarbonate material with excellent heat resistance, cold resistance, and chemical corrosion resistance. The selection of this material enables the membrane switch to withstand various extreme conditions in medical environments, ensuring its long-term stable operation.
Structure and Design: IP67 waterproof membrane switches typically feature a fully sealed design with an overall thickness of 0.5–2 mm. Their structural design includes an upper and lower housing enclosure structure and a mid-frame gasket design, achieving airtight sealing through processes such as hot riveting and ultrasonic welding to prevent dust and water ingress.
Application Scenarios: In medical devices, these switches can adapt to high-humidity and corrosive environments, ensuring stable device operation and operational safety.
Service Life and Maintenance: IP67 waterproof membrane switches offer a long service life and high durability, with standard products capable of withstanding up to 1 million presses. Their structural design enables the switches to withstand frequent operations without damage, reducing maintenance requirements and costs.
