3Keys Membrane Switch Keypads

This type of membrane switch uses silver paste as the upper circuit layer of the switch. By pressing, the center of the silver paste point is connected to the lower circuit to realize the conduction and trigger signal. Through the "die-pressing" , the silver paste disk of the button of the upper circuit is pressed into a certain spherical crown shape with a mold, and a certain elasticity is generated, so that the button can rebound when pressed, and the circuit is turned on or off. It is also obvious enough to feel the switch closed. Bumping of silver paste requires the use of molds, especially batch orders, and the need to customize the bumping molds can greatly improve the production efficiency and the stability of product quality.

This type of membrane switch can be installed with LEDs inside. When the corresponding button is pressed, the LED will light up and be used only as the operating area of â??â??the switch. JRPanel uses Everlight's Everlight package as a 1206 SMD LED. The LED light is welded on the circuit under the membrane switch to assemble it as a whole. The LED light window is often bumped. This type of product is mainly used for the function keyboard of the industrial control equipment of the man-machine interface. JRPanel this product can be welded with LED lights of various colors according to customer needs. (Red, Emerald green, Blue, Yellow green, BI-LEDs, RGB LED).
