ALPS has developed the new TACT Switch™ Surface-mount (equivalent to IP67) "SKTA" series, which is best suited for the side operation of thin smartphones and various wearable devices requiring small size and dust and water resistance, and began mass production in March.

In recent years, smartphones have been emerging with larger screens. In order to facilitate the operation in the hand, and does not affect its operation, the manufacturers need to install the main body of the side part of the thin, curved and other aspects of efforts. In addition, due to the waterproof and dustproof countermeasures of smart phones and small wearable devices, the electronic parts carried by them are required to be small in size and equipped with waterproof and dustproof structure.

In order to meet the market demand, the ALPS companies to develop and start mass production of TACT Switch ™ zone bump SMT type "SKTA" series by the unique design and production technology to achieve the SMT area compared with the previous product reduced about twenty percent (shape size 2.6 * 1.6 * 0.53 mm), at the same time has equivalent to IP67 waterproof and dustproof performance and long life of 300000 times.

In addition, the metal contact is provided with a built-in bulge, which can inhibit the tactile changes caused by the dislocation during assembly, while achieving the operation stability of end press and oblique press, which makes a contribution to the improvement of operability.
