The metal dome, also referred to as stainless steel domes or tactile metal domes, is a crucial component of membrane switch systems. Made from durable stainless steel, metal domes leverage the conductive properties of the material to facilitate electrical connections. Positioned on the silicone membrane keypad, the metal dome sits directly above the conductive traces on the PCB, typically aligning with the gold fingers of the circuit board. When the dome is pressed, its center deforms and creates contact with the PCB traces, completing the circuit. This action allows current to flow and activates the keypad, ensuring reliable and responsive performance.
