Metal dome is made by the stainless steel, and used for the membrane switches.

The principle of metal dome works is that when they are placed on the printed circuit board by means of pressure-sensitive adhesive tape, in their relaxed state, the metal domes rest on the outer rim of the primary pathway. When pushed, the domes collapse and make contact with the secondary pathway, thereby closing the circuit.

Many different shapes and forces of our metal domes are available. We mainly have the four kinds shape: round; four-leg( cross); triangle and oblong, the diameter from 3mm to 20mm, and the force from 80g to 5000g. Platings of the metal domes, such as Nickel plating, silver plating & gold plating are also available.

if you need the metal dome, please contact with us in anytime.
