Coto Technology – Over 60 Years Leading in Precision Switching Innovation


Some companies don’t just make components — they shape entire industries. Coto Technology exemplifies this spirit. For more than six decades, Coto has relentlessly pursued innovation in switching components, guided by one core belief: performance and reliability must go hand in hand.

Founded in 1958, Coto evolved from a reed relay manufacturer in the U.S. into a global benchmark for precision in sectors ranging from medical devices and consumer electronics to industrial measurement and automation. Their quality stems not only from engineering expertise but from a deeply ingrained “Zero Defect” production culture.

Innovation Built Into Every Component

At Coto, each product line represents more than circuitry — it’s a step forward in switching science. Among the standout offerings:

  • Solid State Relays (SSR): Featuring MOSFET technology for contactless switching, these relays offer ultra-long lifecycle, reduced EMI, and rugged mechanical performance.

  • Molded Reed Switches: Fully sealed for harsh environments, widely used in flow, proximity, and security sensors.

Other available solutions include SMT relays, RF relays, and high-speed switching relays, designed to meet the demands of semiconductor testing, aerospace, and defense.


Every Detail Reflects a Long-Term Strategy

Coto doesn’t chase mass production. Each relay and switch undergoes rigorous testing in ISO Class 100,000 cleanroom environments. Comprehensive quality programs like Total Quality Management (TQM), Lean Manufacturing, and a commitment to Continuing Innovation ensure component-level consistency — a non-negotiable in precision test systems or critical medical devices.

Although Coto’s components are embedded in millions of electronics worldwide, users rarely notice — because they run silently, reliably, and failure-free. In microelectronics, that’s the ultimate mark of success: when the technology performs perfectly without drawing attention.
