The Lamar X61-0031 Contactor is an aviation-grade 24 VDC intermittent-duty starter relay designed for high-current switching in aircraft electrical systems. It serves as the interface between the aircraft's low-current control circuit and the high-current starter motor circuit, providing dependable engagement during engine starting while protecting the electrical system from excessive current through the cockpit controls.

Built for demanding general aviation applications, the contactor features a normally open (N/O) configuration and is engineered to withstand the high inrush currents associated with starter motor operation. Its robust internal contacts and durable coil assembly provide reliable switching performance under repeated start cycles while maintaining consistent electrical conductivity and long service life.

The X61-0031 is suitable for installation in compatible 24-volt aircraft electrical systems and is commonly used as a replacement for both legacy single-terminal and newer dual-terminal starter contactors. It is intended for intermittent operation only and should be installed and maintained in accordance with the applicable aircraft maintenance documentation and approved procedures.
