September 20, 2006, Osaka, Japan－Panasonic Electronic devices Co., Ltd. has succeeded in commercializing the 4 mm square double-action light touch switch with the industry's smallest switch size as a operational device of an auto-focus shutter function used for digital still-cameras and mobile phones, which distributes to downsizing and low-profiling devices.

In mobile phones with the camera function, double-action switches which realize an auto-focus function as well as digital still-cameras have been required, and also as devices have become smaller with multi-functions, double-action switches have been to be smaller, thinner, and have a longer life. We have succeeded in achieving the industry's smallest switch size by combining two-movable contacts optimally, using our original structure laminating two-movable contacts. The structure isolating two-movable contacts eliminates the mutual interference and provides a longer life.
