High-current relay for searchlight or air conditioning systems — 12VDC / 24VDC operation, 40A capacity. One unit is available configured for 12VDC operation. Key benefits Reliable high-current switching: 40A capacity handles heavy loads without overworking control switches or low-current wiring. Flexible power compatibility: accepts either 12VDC or 24VDC input, making it usable across common mobile and industrial electrical systems. Simple replacement or upgrade: fits typical relay applications for searchlights and air conditioning systems, reducing downtime when a switching component fails. Protects control circuits: offloads current draw from toggles and control modules to the relay, improving system longevity. What it does (function) Electrically switches power to a searchlight or an air conditioning component on command from a low-current control circuit. Suitable wherever a separate high-current switching device is required to control heavy electrical loads. Compatibility and performance Coil voltage: available for 12VDC operation (one piece). The relay type also supports 24VDC systems where applicable. Current capacity: rated for 40A continuous switching, appropriate for high-draw accessories such as powerful lights and compressor circuits. Designed for use in systems that require durable, repeatable on/off switching of DC power. Practical considerations (installation & safety) Match coil voltage to your control circuit (12VDC unit available). Using the correct coil voltage is essential for reliable operation. Always include appropriate fuse or circuit protection sized to the load and wiring. Recommend professional or experienced installation to ensure correct wiring and secure mounting. Example applications Vehicle-mounted searchlight: switch the searchlight from a dash control without routing full load current through the switch. Mobile air conditioning: control a compressor or condenser fan in a 12V or 24V mobile HVAC setup while keeping control circuitry low-current. Auxiliary power circuits: use to switch other high-current DC accessories in service vehicles, boats, or industrial equipment where 12V/24V supplies are used. Availability One piece available configured for 12VDC operation. Confirm coil voltage and wiring needs before purchase.
