What brand of relay is good?

No brand is good, no brand is bad, just choose the relay that suits you. At present, the well-known relay brands in China are Sanyou, Le Song and Hongfa. Now the production lines on the market are almost the same, the relay production technology is also very mature, the materials of parts are almost uniform and the technology is also very mature. So when choosing a relay, you don't need to think too much about the brand. You can consider more second-tier brands like Tengfei and Tongling. The quality of many products exceeds these first-line brands.

Now every manufacturer can provide samples, and can ask many companies for samples, compare the cost performance, and choose the most suitable relay.
