Graphic Overlay Layer
The graphic overlay layer is the topmost layer of the membrane switch assembly and serves as the visual interface. It contains the graphical elements, such as icons, labels, and other visual cues, representing the interactive elements available to the user.
Overlay Adhesive Layer
The overlay adhesive layer is a thin adhesive material applied to the back of the graphic overlay. It securely bonds the graphic overlay to the layers below and ensures its proper alignment and positioning.
Static Shield Layer (optional)
ESD (Electrostatic Discharge) shield layer, is an optional layer that can be included in a membrane switch assembly. It is designed to protect the switch and its internal components from damage caused by electrostatic discharge.
The static shield layer is typically made of a conductive material, such as a metal foil or conductive film, that has low surface resistivity. It acts as a barrier, dissipating any static charges that may build up on the surface of the membrane switch. This layer helps prevent the discharge of static electricity, which can potentially harm sensitive electronic components or disrupt the proper functioning of the switch.
Dome Retainer Layer
The dome retainer layer, also known as the upper circuit layer, is typically made of a rigid material such as polyester or polycarbonate. It provides support and alignment for the dome switches (also known as tactile domes) found in the membrane switch.
The spacer layer is a thin material that provides separation between the graphic overlay layer and the lower circuit layers. It ensures that the graphic overlay layer remains in place and prevents accidental actuation of the switches.
The circuit layer comprises conductive traces and contacts, typically made of silver conductive ink, etched copper flex or printed circuit boards (PCBa’s). The circuit layer defines the layout and position of the interactive elements (buttons, switches, etc.)
Support Backer Layer (optional)
The backer layer is the bottommost layer of the membrane switch assembly. It provides additional support and protection to the assembly. The backer layer may also include mounting features or adhesive backing for attaching the assembly to a surface.
