C&K Components is one of two operating divisions (the other being Delta Tech Controls) of CoActive Technologies, a designer and manufacturer of a broad range of engineered interface solutions. C&K Components focuses on switches, smart card connectors, and high-reliability connectors. The company was established in 1957 in Newton, Massachusetts as a manufacturer of magnetic computer memory units. The company has since combined with other specialty companies to become an important supplier of interface and connector technology. In 2007, C&K Components joined the Rudolf Schadow Company of Berlin, Germany (founded in 1945 and specializing in radio repair) and the Jeanrenaud company of Dole, France (a switch manufacturer founded in 1928) to form a new company while retaining the C&K Components name.
