Membrane switch is an operating system with key function, indicator and instrument panel. It consists of panel, upper circuit, isolation layer and lower circuit. When the membrane switch is pressed, the contact of the upper circuit deforms downward and contacts with the plate of the lower circuit. After the finger is released, the contact of the upper circuit rebounds back, the circuit is disconnected, and the circuit triggers a signal. The membrane switch has rigorous structure, beautiful appearance and good sealing performance. It has the characteristics of moistureproof and long service life. Widely used in electronic communication, electronic measurement instruments, industrial control, medical equipment, automotive industry, intelligent toys, household appliances and other fields.
The benefits of membrane switches include ease of cleaning, sealing ability and their low profile. Membrane switch can be used together with other control systems such as touch screens, keyboards, lighting, and they can also be complicated like the membrane keyboards and switch panels in mobiles and computers.
Without employing external sealing methods, membrane switches are limited by the pressure sensitive adhesives used in construction. The adhesives can be water resistant but are not completely waterproof.ploying external sealing methods, membrane switches are limited by the pressure sensitive adhesives used in construction. The adhesives can be water resistant but are not completely waterproof.
With all of the uses for electronics that contain membrane switches, it is possible that they will be exposed to water or even to liquid solvents. Product failure is not an option when it comes to the environments that require waterproof membrane switches, such as medical, military, harsh industrial, transportation, and material handing environments. To avoid disaster, it is crucial for the electronic components to be sealed so that they are protected. With the proper design and use of adhesives, rubber membrane switches can be waterproof.
