Function: 1. 4 relay terminals have been sealed and the performance is more stable. 2. Compared with bare copper wire, tinned copper wire ma stronger and better conductivity dla corrosion resistance and oxidation resistance. 3. They have good sealing properties and very strong, with excellent waterproof and dustproof properties. 4. Have humanized projekt, simple operation, easy to install, convenient to use and operate. 5. Small size and light weight, convenient do carry and use at any time, very convenient and practical.
