What is the working principle of membrane switch design



Before we understand the working principle of the membrane switch, we should first understand the components of the membrane switch. Only when we understand the composition of the membrane switch can we better understand the working principle of the membrane switch. We ask the staff of the membrane switch manufacturer to introduce it to everyone.

In general, the common membrane switch is mainly composed of 6 layers of materials, which are panel, surface glue, upper circuit, isolation layer, lower circuit and primer in the order from the top to the bottom.

The basic working principle of the membrane switch is as follows: when the panel is not pressed, the membrane switch is in a normal state, the upper and lower contacts are in a disconnected state, and the isolation layer isolates the upper and lower lines; when the panel is pressed, the upper panel The contact of the circuit is deformed downward, and the line is re-combined with the lower line to make the line conductive. The line after the conduction is signaled to the externally connected instrument (substrate) to realize its corresponding function; when the finger is released, the upper circuit touches The point bounces back, the circuit is broken, and the loop triggers a signal.
