Our snap domes are applied to PCB, membrane, or flex circuit by means of pressure-sensitive adhesive tape. Several standard material options are available, as well as custom materials. Such as the domestic adhesive tap, 3M adhesive tap.
We name this product is metal dome array, peel off the support paper to stick on your PCB, FPC or membrane switches. See our dome arrays for more information or see the the assembling instruction of dome array.
Snap dome as the most important part of the switches, the life cycle is considered to be improtant too.
Our snap domes have the high quality and competitive price compare to Snaptron. Many customers use our snap dome replace of Snaptron metal domes. we have a very strict quality control system to ensure high quality.
Our snap domes with high life cycles, such as the cross snap domes, most itesm of the life can reach to one million times. Snap dome life cycle is determined by the material, mold design,and the experience of engineers and so on.

Do you know the snap dome specifications before you purchase? Ok, if not, please follow me to know what you should to be known:
1. Snap dome material: our stainless steel of metal domes are made from type 301 SUS. We purchase the material from USA and Japan.
2. Material thickness: Normally, the thickness is 0.06mm, 0.08mm, 1.0mm, 1.2mm.
3. Click ratio of the metal dome: CC: Click Ratio; CP: Compression Peak Force; CL: Compression Low Force; RL: Release Low Force; RP: Compression Peak Force
CC(%)=(CP-CL)/CP x 100%, it’s normally between 35% and 60%.
4. Height: The height is equal the stoke + thickness of the metal dome.
5. Life Expectancy: Life cycles of our metal domes are from 10,000 to 100,000 times.
6. Platings: There are three types for plating: Nickel plating, silver plating and gold plating are available.
7. Usages: Metal domes are widely use in the swithces, such as the phone, Mp3, Mp4, Microwave oven, toys, remoted controller, and Medical equioments, and etc..
Are you clear now? If not, never mind, please contact our professional sales, we will do our best service for you. CMD Manufacture has over 10 years in this industry.
Maybe some customers want to know if there is relation between Snap dome diameter and thickness of material.
Snap dome, also named metal dome, we have circle shape, four-leg shape, triangle shape, and oblong shape. The diameter from3mm to 20mm. You can see below rough thickness of material for different diameter:
1. 3mm-5mm diameter snap dome, normal use the 0.04mm-0.06mm thickness of stainless steel material;
2. 6mm-8mm diameter snap dome, normal use the 0.06mm-0.08mm thickness of stainless steel material;
3. 9mm-12mm diameter snap dome, normal use the 0.08mm-0.10mm thickness of stainless steel material;
4. 16-20mm diameter snap dome, normal use the 0.10mm-0.12mm thickness of stainless steel material;
The bigger diameter snap dome, the thickner material. The material also determine the quality of snap dome. Material of choice was out of our practical production.
