Membrane switch is a key function, indicating device, instrument panel for the integration of an operating system. Is composed of panel, circuit, isolation layer, the circuit on four parts.
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.
With the characteristic of moisture proof, long service life, etc. Membrane switch is widely used in electronic communications, electronic measuring instruments, industrial control, medical equipment, automotive industry, intelligent toys, household appliances and other fields.
Membrane switch, the basic working principle is as follows: when the panel is not pressed, membrane switch is in normal state, the upper and lower contact shows off state, isolation plays a role of isolation layer on top and bottom line. When the panel is pressed, the circuit of the contact deformation down, and the circuit merge in making circuit conduction, after conducting lines to the external instrumentation (substrate) to signal, so as to realize its corresponding function; After the fingers, contact bounce back on the circuit, circuit disconnect, loop to trigger a signal.
