DSMI group
Originally active in IC sockets, PCB and coaxial connectors, the society DSMI electronics SA has, along the years, diversified its activities. In 2004, DSMI acquired Precicontact and all his manufacturing equipment, processes and stocks. Two years later, DSMI opened an anglage department for watchmaking, a key industrial sector in Switzerland. Meanwhile, DSMI took part in developping a new patented product invented by two young swiss engineers: The SnowPulse Avalanche Air Bags.
