1. The relay casing is made of high - quality materials. It has excellent electrical conductivity, wear - resistance, and fast heat dissipation, which can reduce temperature rise. It can maintain a good conductive contact state and has a long service life.
2. The 5 - pin design of the starter relay allows for more complex circuit control logic, meeting the diverse electrical control needs of vehicles.
3. The relay is easy to install. Just directly insert its terminal pins into the corresponding grooves to complete the installation.
