Augeny 2 PCS 40A Car Relay, 4 Pin 12V Automotive Switches and Starters, Model JD2912-1H-12VDC 40A 14VDC, Universal Multi Purpose Heavy Duty Standard Relay for Car Motorcycle Boat

【Practical Function】: Automotive relays control the current of high-voltage lines by controlling the current of low-voltage lines and play the role of current switches. Its main function in automobiles is to start the motor to rotate by making the small current control the large current, thereby driving the magneto rotor inside the generator to rotate.
【High Quality】: The plastic shell of the relay is waterproof, and the brass pins are electrically insulating and flame retardant, so they will not malfunction or short circuit easily. Silver contacts have good electrical and thermal conductivity and are not prone to rust, corrosion or oxidation. Equipped with a full copper electromagnetic coil, the temperature rise is lower and the suction power is stronger. It can withstand larger currents and has more stable working performance.
【Easy to Carry & Install】: The size is 2.05×1.13 inches. The compact design is very convenient to carry and can be placed in the tool box without taking up much space. It is suitable for ordinary cars and is simple to operate. You only need to connect the relay with wires, no other tools are needed, making it easy for you to use and replace, so that your parts can work properly.
【Two Models】: There are two models for you to choose from, 4-pin and 5-pin, please purchase according to your needs. The 4-pin model is JD2912-1H-12VDC 40A 14VDC, and the 5-pin model is JD2912-1Z-12VDC 40A 14VDC. They're both sensitive to turn on, the start time is less than or equal to 10ms, and the release time is less than or equal to 5ms, providing excellent work performance.
【Widely Used】: It is a very universal car accessory. It is widely used to install electric cooling fan, electric fuel pump, electric water pump, trunk solenoid, horn and so on. You can also use it for car lighting system, engine compartment electrical box, air conditioning system, circuit modification and other devices.
