Membrane Switch
Five kinds of main mambrane switch, and their features, applied scope, technical parameters and remarks.
A. 3-D Hand/Feel Membrane Switch
B. Plane Light-touch Membrane Switch
C. LED Illuminated Membrane Switch
D. EL Noctilucent Membrane Switch
E. High-performance Waterproof Membrane Switch
A.3-D Hand/Feel Membrane Switch
1.Features: Raised 3-D sense of the surface keystroke on the panel, built-in metal dome or plastic dome and touch sense while pressing the keystroke.
2.Applied Scope: Switch keystroke of all microelectronic controller.
3.Technical Parameters: Service life longer than 500,000 times, maximum working current being 10VCD100MA and operating force being 250-550G.
4.Remarks: The raised on the surface of the keystroke can be made as per customer requirements.
B.Plane Light-touch Membrane Switch
1.Product Features: Long service life, no sense while pressing the switch and small operating force.
2.Technical Parameters: Service life longer than 1,000,000 times, maximum working current being 10VDC100MA and operating force being 30-150G.
3.Applied Scope: Switch keystroke of all microelectronic controller.
4.Remarks: Operating force can be adjusted as per customer requirements.
C.LED Illuminated Membrane Switch
1.Product Features: Built-in LED indicating illuminating tube makes processing and design of your product easier and more convenient.
2.Technical Parameters: Maximum working current being 6VDC100MA and switch thickness being 0.8-2.5MM.
3.Applied Scope: Switch keystroke of all microelectronic controller.
D.EL Noctilucent Membrane Switch
1.Product Features: Built-in large area of EL noctilucent sheet, which makes it quite easy to press the keystroke at dark night.
2.Technical Parameters: Working voltage being 30-250VAC, service life longer than 10000HRZ and working temperature being -40 degree---60 degree.
3.Applied Scope: Various electronic products used when there is no enough light.
E. High-performance Waterproof Membrane Switch
1.Product Features: High-performance waterproof material adopted makes the product be used in 95% of damp environment.
2.Technical Parameters: The performance is the same with that of common membrane switch.
3.Applied Scope: Electronic products used in damp environment, such as electronic switch in steam sauna room and bathroom.
