CTS

Cts Corporation

A maker of sensors, actuators, and electronic components that help machines "sense, connect, and move," CTS supplies original equipment makers in aerospace, medical, industrial, and automotive fields. Founded in 1896 as the Chicago Telephone Supply Company by a father-and-son team, it built the magneto-driven telephones and switchboards of the early phone era. When the business outgrew its Chicago shop, the city of Elkhart, Indiana, lured it there in 1902 with a building on a railroad spur, and the name was shortened to CTS in 1960.
