After analysing and evaluating on the spot, we fully reuse the old relay.



We design one more PCB board,and weld the relay on it. The old relay body and protection circuit are retained. Also we do not change the original mounting position.

Throughly solve the relay falling-off situation. And this mode of relay installation obtain a good expansibility.
