- Description
Relays and Contactors are electromechanical switching devices designed to perform control, protection and power distribution functions within aviation onboard electrical systems. These components are used to engage and disconnect electrical circuits, control power supply to equipment, protect systems from overloads and ensure stable operation of aircraft electrical networks under varying load conditions. Relays and contactors within this category are applied across avionics systems, power distribution panels, engine start circuits, lighting systems, control networks and auxiliary onboard equipment in both helicopters and fixed-wing aircraft. Low-current relays are used for signal switching, logic operations and precision control tasks, while time relays provide delayed activation or deactivation for systems requiring controlled timing sequences. Contactors are designed for switching higher-power electrical circuits, main loads and auxiliary consumers where increased current capacity and stable contact performance are required. These units are engineered for reliable operation under vibration exposure, temperature fluctuations, electrical load variations and continuous duty cycles typical for real aviation environments. The manufacturing concept is based on reinforced contact groups, stabilized electromagnetic drives, arc-resistant materials and vibration-resistant housings to ensure predictable switching performance and long-term operational reliability. Relays and contactors supplied in this category are available in New, Serviceable and Overhauled condition, with verified manufacturing origin or maintenance traceability and full technical documentation upon request. This category is intended for electrical system replacement, control circuit modernization, scheduled maintenance and fleet-level refurbishment programs. Logistics support is provided through fast international dispatch from UAE and EU stock hubs for MRO companies, fleet operators and aviation trading organizations seeking reliable switching solutions for aircraft electrical systems.
