Do the different shapes and diameters snap domes can make into one metal dome array?

Wednesday, December 4th, 2013

Do the different shapes and sizes snap domes can make into one metal dome array? Answer is yes. For example, round and oblong snap domes, cross and triangle snap domes can make into one metal dome array.

Why do customers have this request?

1, Maybe customers’ pcb board design problems. For example, it can not use round snap dome for single pcb board, so that we can use oblong instead of.
2, Different click feeling required. Some require higher force, others require better click feeling;
3, Rubber key size. That require the different diameter of snap domes.

Although this metal dome array that can be made, the process of making is a bit more complicated, we need to make two assembly toolings and more time to assmble.So you can see the price should be higher. Therefore, we recommend: if you don’t have special requirements, please use one shape and diameter snap domes.

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.

Which metal snap domes for cellphone?

There are normal circle and oblong shape metal domes. They are also normally made into the EMI dome array to assemble on the phone. Early, cellphone metal domes are two kinds, with or with one dimple, but now with the technology developing, there are also with three dimples, four dimples, five dimples happened in 2009. More dimples, better click feeling, but the life is a little less than before.

Circle metal dome: 3mm, 3.5mm, 4.5mm, 5mm are most used; Oblong metal dome: 5.0mm*3.8mm, 4.0*3.0 are most used.
