- Coto Technology Inc. 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 in 1994. In 1998 Coto acquired the Philips Dry Reed Switch Division in the Netherlands to form Coto Technology, B.V. Through the acquisition of the assets of SRC Devices in 2007, Coto further expanded its reed relay line and added DYAD™ switches to its offerings.
