PCB Tactile Membrane Switch for Smart Car Keyboard

A membrane switch is an integrated operating system that combines key functions, indicator elements, and a control panel. It consists of four main parts: the panel, top circuit, isolation layer, and bottom circuit. When the membrane switch is pressed, the contacts on the top circuit deform downwards, making contact with the board on the bottom circuit.

Uses of PCB Membrane Switch

A PCB (Printed Circuit Board) membrane switch is a type of switch that uses a PCB circuit as the support substrate. It typically consists of multiple layers, including a top graphic overlay, a spacer layer, and a bottom circuit layer. The graphic overlay is the visible layer with the printed symbols or graphics representing the keys.

The key function is achieved through the use of conductive traces on the bottom circuit layer. When a key is pressed, it causes the top and bottom layers to come into contact, completing the circuit and registering the keypress. Membrane switches are known for their slim profile, durability, and resistance to environmental factors like moisture and dust.

These switches are commonly used in various electronic devices such as remote controls, medical equipment, industrial controls, and consumer electronics where a compact and reliable keypad or keyboard is required.
