The wiring method is very simple, just connect the normally open line to the common line, and then connect one to the power zero line, and the other line to the fire line. But it should be noted that if the rated current of the appliances used is high-powered, AC contactors should be used.
What are the features of the foot switch?

If it is a foot switch in the welding field, it also has the effect of controlling the output current size. The application in the electronics industry, the terminal machine configuration, respectively, automatic, inching, inching refers to the application of the foot switch. Step on it to start a period of travel.
Foot switch precautions
1、When using the foot switch, the rated load of the product should be determined according to the nature of the load and the size of the current value.
2、During handling and moving, attention should be paid to the short circuit and disconnection of the internal wiring.
3、If there is a lot of water, oil or dust in the place itself, pay attention to the protection level of the product.
