Membrane switch is a key function, indicating device, instrument panel for the integration of an operating system, so, let's say it together features:
Membrane switch by the panel, the circuit and isolation layer, the circuit of four parts. For light touch type is normally open to switch, normally membrane switch of upper and lower contact in off state. Press the membrane switch, circuit contact deformation, down on the pad of the circuit under contact conduction, fingers, contact bounce back on the circuit, circuit disconnect, loop to trigger a signal. Membrane switch structure is rigorous, beautiful appearance, good sealing. Has the characteristic of moisture proof, long life and other characteristics, widely used in electronic communications, electronic measuring instruments, industrial control, medical setting
Membrane switch is also called light touch keyboard, using a combination of planar multi-layer whole sealing structure, is to button switches, panels, tags, symbols show and liner seal together the set of optical, mechanical and electrical integration of a new type of electronic components, electronic product appearance structure of fundamental change, it can replace the conventional discrete component key, more reliable ways to perform the task of the operating system.
Membrane switch has a good waterproof, dustproof, prevent oil, prevent harmful gas erosion, stable and reliable performance, light weight, small volume, long service life, convenient assemblies, the panel can be washing and character is not damaged, color is rich, beautiful and easy, etc. Using membrane switch make your product more age characteristic, main types of membrane switch membrane switch
