Product Description
Metal Dome Silicone Rubber Keypad Membrane Switch
Professional silicone rubber keypad membrane switch with 3M9080 adhesive PET backing, designed for reliable tactile response and long service life in industrial applications.
Product Structure
Our membrane switches feature a five-layer construction: graphic overlay, adhesive layer, metal dome, circuit layer, and back adhesive. The silicone rubber keypad design incorporates gradient webbing around button centers that deforms when pressed, providing positive tactile feedback and returning to neutral position when released.
