## Long description

BLOW 2639# is a compact 12 V electromechanical automotive relay designed for switching and control of low-to-moderate current loads. The NT73-2 model delivers a rated switching current of 10 A at 12 V DC and is intended for on/off control within vehicle electrical systems and auxiliary circuits. The relay features a standard footprint suitable for common automotive sockets and replacement applications where a reliable, simple switching device is required.
Advantages
The relay offers reliable mechanical switching with a 10 A rated contact capacity at 12 V DC, providing an effective solution for many auxiliary circuits. Its compact form factor and standard pin arrangement simplify installation and replacement in wiring harnesses and relay panels. Being an electromechanical design, it provides clear open/close states and straightforward compatibility with existing automotive control circuits.
Suitable for
Switching automotive lighting circuits (auxiliary lights, fog lights)
Controlling low-current electric fans and pumps
Integration into vehicle relay blocks and wiring harness replacements
Accessory and aftermarket electrical installations that require a 10 A 12 V relay
Key specifications
Nominal coil voltage: 12 V DC
Rated contact current: 10 A
Relay type: electromechanical (single pole, single throw or equivalent common automotive switching configuration)
Typical application: automotive and auxiliary vehicle circuits
Physical form: compact automotive relay with standard pin layout for common relay sockets
How to use
Install the relay into a matching 12 V automotive relay socket or insert it into the vehicle’s relay block following the original relay orientation. Connect the coil terminals to the control circuit (12 V supply and ground as appropriate) and wire the contact terminals in series with the load to be switched. Verify proper parking of pins and secure electrical connections to prevent corrosion and intermittent contact. Test the circuit operation by energizing the coil and confirming that the connected load turns on and off as expected.
Usage recommendations
Use this relay within its specified rating: 12 V coil voltage and a maximum of 10 A switching current. For loads approaching the maximum current, ensure adequate fusing and consider using a relay with a higher current rating or a contactor for prolonged high-current applications. Keep the relay and socket terminals clean and free of moisture to maintain reliable operation.
