Coto Technology, a division of Kearney National, Incorporated (headquartered in White Plains, New York, USA) originated in Providence, Rhode Island in 1917 as Coto Coil Incorporated - a company specializing in the design and manufacture of coil windings. During the mid-1960's, Coto expanded its product line by introducing the reed relay - the result of integrating reed switches into coil windings. By 1970, Coto emerged as a leading manufacturer of reed relays with the development of the first patented Low-Thermal EMF reed relay. Coto went on to produce the first ever surface-mounted reed relays in 1983 and world's smallest reed relay in1994. In 1998 Coto acquired the Philips Dry Reed Switch Division in the Netherlands to form Coto Technology, B.V.
