Top Layer: Made of flexible rubber or silicone, this is the visible surface where the user interacts. It often features printed symbols or labels.
Spacer Layer: This layer prevents accidental activation of the switches when they are not being pressed. It contains openings that align with the buttons on the top layer.
Circuit Layer: This layer includes conductive traces that connect the switches to the device's electronics. When a button is pressed, the top layer makes contact with this layer, completing the circuit.

Durability: Rubber keypads are resistant to dust, moisture, and chemicals, making them suitable for harsh environments.
Tactile Feedback: They provide a satisfying tactile response, allowing users to feel when a button is pressed.
Customization: These keypads can be easily customized in terms of layout, color, and design.

Rubber keypad membrane switches are commonly found in:

Labels spec :

Material

Common materials include vinyl, polyester, polyimide (Kapton), and polyethylene terephthalate (PET) films.
The material needs to be durable, chemical/solvent resistant, and able to withstand temperature extremes.

Adhesive

Pressure-sensitive adhesives like acrylic or rubber-based are common.
The adhesive must have strong bonding strength to adhere securely to various surfaces.
It should also resist peeling, lifting, and degradation over time.

Thickness

Typical sticker thicknesses range from 2-10 mils (0.002" to 0.010").
Thicker stickers are more durable but may impact conformability to uneven surfaces.

Size & Shape

Industrial stickers come in a wide range of standard and custom sizes.
Common shapes include rectangles, squares, circles, ovals, and die-cut custom shapes.
Size is selected based on the specific application needs.
