Silicone Rubber Keypad PET metal dome membrane circuit

Rubber keypad switch structure and switch assemblies

As we all know, the general membrane keypad has five layers. Graphic overlay, the adhesive layer, metal dome, circuit layer, and back adhesive. Assemble these layers together, membrane switches with tactile response are made. Benefit from the use of metal dome, you have the tactile feel when pressing the key top to function. And the service life of membrane keypads also depends on it. For the silicone keypad switch, the graphic overlay layer uses rubber material. And it always uses a printed circuit board as a circuit layer.

Using compression molding properties of custom silicone rubber material, the supplier creates gradient webbing around the button center. After pressing down the button, the web deforms to produce a tactile response. Remove the actuation force from the switch the webbing returns to its neutral position with positive feedback. For consumer and industrial electronic products, the carbon pill or metal dome is adopted to contact the printed circuit board when the web has been deformed to conduct electricity. Huaisong Industrial, which designs and manufactures cost effective silicone keypads since 2010, can also make membrane switch assembly.
