Membrane switch is an operating system that integrates key function, indication element, and instrument panel. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. When the membrane switch is pressed, the contacts of the upper circuit are deformed downward and contacted with the pole plate of the lower circuit for conduction. When the finger is released, the contacts of the upper circuit rebound back and the circuit is broken, and the circuit triggers a signal. Membrane switch has strict structure, beautiful appearance and good sealing.

Membrane switches are moisture-proof and have long service life.

Membrane switches are widely used in electronic communication, electronic measurement of instruments, industrial control, medical equipment, automotive industry, intelligent toys, household appliances and other fields.

Membrane switch in the circuit layer of the membrane, consider the separation of switch contacts, rebound and the reliability of the lead to the connector plugging or riveting, so the thickness of the circuit material should be selected between 0.125 mm to 0.15 mm is appropriate. Too thin is no rebound, the separation of contacts is not agile, too thick, the action is sluggish and increases the operating effort.

From a specific point of view, the selection of the thickness of the membrane switch is also related to the following factors.

    1. The thickness of the isolation layer.

    2. The shape of the key body.

    3. The size of the key body.

    Therefore, it is appropriate to choose 0.125mm thickness for the material of membrane switch circuit layer. Shanghai Xiangming will answer your questions about membrane switches one by one.
