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

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.
