Snap Domes
Snap domes (also named metal domes, tactile domes)are the most important part of the switches which used in conjunction with a printed circuit board, flex pcb, or membrane.
The principle of metal snap 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 snap 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 snap domes are available in order to meet customers’ applications. 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.

C-series snap domes(metal domes) are the circle or round shape which can be used in 2-layer printed circuit board. Thery have a "softer" click feeling with lower force...
The size of the F-series snap domes is from 5mm to 20mm, the force is from 100g to 600g. diameter we have 6mm, 7mm,8.4mm, 10mm, 12.2mm,16mm,20mm....
We have the diameter of T-series is from 4mm to 12mm, and the force is from 100g to 5000g. T-series in the same diameter is that with the higher actuation force...
O-series snap domes(metal domes) are the oblong shape switches that are designed widely used in the long and narrow space for the PCB, FPC, membrane switches...
Beside the standard snap domes, we also offer make custom snap domes according to customers' design...
