Development of "DSK Series" Detector Switch with Improved Space-saving and Operability

 We are pleased to announce the development of our industry-smallest "DSK Series" detector switch.
 This product reduces the size (16% reduced volume) of our existing product (DSI Series), and lengthens the full-stroke by 1.6mm and the on-stroke by 1.2mm, contributing to improved design freedom.
In line with a trend in recent years for smaller and thinner mobile phones and portable audio equipment, similar demands for electronic components have increased. As the number of high-performance and large memory capacity equipment such as smartphones increase, there is greater demand for detector switches to be installed in a large amount of equipment. These switches can detect the opening and closing of battery packs and memory card covers, helping to prevent the sudden loss of important memory caused by incorrect operation.
Detector switches are used not only for detection but also for battery charger and liquid crystal display rotation, and sometimes as a substitute for slide switches.
 We intend to expand our switch operations through the continued and proactive development of new products.
