I have a pressure switch on the cylinder where the air pump and pump are connected. When the pressure in the cylinder reaches 4KG, the pressure switch will be automatically disconnected and the pump will be shut down. The air pressure will drop to 2KG. The question now is: the pressure switch is 24V, the pump is 220V, please master guide how to connect this switch and air pump to control the off? Thank you
Please try to say that some, I am not engaged in electronic electrical, afraid to understand do not understand. Also do not want to change the 220V pressure switch, because the hands of the cylinder is the original, screwed in the cylinder reserved hole, very small, as shown
Or is this a pressure sensor? Seek expert guidance to provide programs
Look at the picture, are you a stress sensor?

I do not know Taobao to buy. The Seek guidance
The pressure switch is connected to the coil of the intermediate relay, and the 220V circuit is controlled by the contact of the relay.
Intermediate relay is twenty or thirty dollars!
Very simple way: 24V pressure switch with an intermediate relay, indirect control 220V circuit on it!
