Detailing how to use the membrane switches correctly

- Apr 06, 2017 -

When the panel is not pressed, the film switch is in the normal state, the upper and lower contacts are disconnected, and the isolation layer plays an isolating role in the upper and lower circuits; When the panel is pressed, the contact point of the circuit is deformed downward. With the next line coincidence and make the line guide, the circuit after the external connecting instrument (substrate) to signal to achieve its corresponding function; When the finger is loosened, the circuit contact bounces back, the circuit is disconnected, the loop triggers a signal.

However, must be placed in the flat place to operate, do not take in the hands of a thin air operation, so not only damage the circuit, but also damage shrapnel, resulting in no rebound elastic. Many customers may not understand, so cause damage, so that we all cause unnecessary losses.
