How to wire the household contactor?

One, the main circuit part

Household contactors have two normally open contacts: one end is connected to the live and neutral wires of the power supply, and the other end is connected to the live and neutral wires of the load.

Second, the control circuit part

1. Connect in sequence: power line → contactor coil → stop button (normally closed) → start button (normally open) → power neutral line. (You don’t have to follow this order, you can shuffle the order, just connect in series)

2. The third normally open contact of the household contactor: connect the two ends to the two ends of the start button with wires. That is to say, where the two ends of the start button are respectively connected, then the two ends of the third normally open contact of this contactor are connected respectively.
