Expansion of Repertoire of Standard “1-Dome Switches” with the Addition of a Coverless Type Switch

 In response to market needs, we are pleased to announce that we have added a “coverless type” product to our repertoire of standard “1-dome switches”, which have been selling well in the smartphone market, in order to further improve sales.
In recent years, there has been increased demand for smaller and thinner electronic components in line with the increased compactness and thinness of equipment. The higher reliability of switches is particularly sought after, such as preventing switches from becoming detached from the PWB caused by equipment being dropped when assembling or using it.
While the 1-dome switches we have already promoted responded to the above mentioned market needs, this product further contains mounting height by employing a coverless structure.
This product will be exhibited at the combined IT and electronics “CEATEC Japan 2010” exhibition held from 5th October, after which we will proceed with full-scale sales activities.
