Flexible Custom Metal Dome Silicone Rubber Keypad

Overview:

The metal dome silicone rubber keypad integrates key functionality, indicator elements, and instrument panel controls. Comprising a panel, upper circuit, isolation layer, and lower circuit, it operates by pressing the silicone rubber surface. Upon pressing, the metal dome deforms downward, establishing conductivity between circuits. Renowned for its robust structure, sleek appearance, and superior sealing performance, it offers exceptional waterproofing and durability. Widely used in electronics, industrial control, medical devices, automotive, and more.
