The advantages of Membrane Keyboard are good water resistance, smooth overall, small quality, thin appearance, good dust-proof, is a semi-closed structure. Widely used in desktop computers, copiers, fax machines, toys, square computers, word processors and other fields. Additional, the design of face plate, color choice has very big freedom.
Membrane Switch is an operating system that integrates key functions, indicating elements and instrument panels. 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 are in contact with the pole plate of the lower circuit. After the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the circuit triggers a signal.The membrane switch has strict structure, beautiful appearance and good sealing performance.
We are a Membrane Switches manufacturer engaged in Graphic Overlay,Membrane Panels, Soft Circuits, Silicone Rubber Keyboard, LED , LGF Silicone Rubber Keypad ,. All kinds of customization, welcome to come to consult.
