Customizable Design Legend Printing Electronical Membrane Tactile
Snap Domes Keyboard
legend membrane switch, also known as a graphic overlay or graphic
membrane switch, is a type of membrane switch that incorporates
custom graphics, text, or symbols onto the switch surface. Here are
the key details about legend membrane switches:
Construction:
Consists of multiple layers, including a graphic overlay, a spacer
layer, and the membrane switch itself.
The graphic overlay is the top layer, which displays the custom
legend (text, icons, symbols, etc.) that indicates the function of
each switch area.
The spacer layer sits between the graphic overlay and the membrane
switch, providing separation and definition for the individual
switch areas.
The membrane switch layer is the bottom layer, which contains the
conductive traces and dome switches that detect the user's input.
Customization:
The graphic overlay can be customized with a wide range of designs,
including logos, instructions, labels, and other graphical
elements.
Printing techniques such as screen printing, digital printing, or
hot-stamp printing can be used to create the desired graphics.
The material for the graphic overlay can vary, including polyester,
polycarbonate, or other durable and scratch-resistant films.
Key Features:
Provides a clear, intuitive, and visually appealing interface for
the user.
Allows for seamless integration of graphics, text, and
functionality on a single surface.
Enhances the overall aesthetics and branding of the device or
product.
