The working principle of foot safety switch and its internal structure
The safety foot switch is a switch that controls the circuit by stepping or stepping on the foot, and is used in the control circuit that cannot be touched by the hands to achieve the purpose of operation instead of the hands.
The simple and safe foot switch is actually a built-in travel switch, and when the foot gives a signal, the switch is executed. However, the function of the foot switch in the welding field also plays the role of controlling the output current.
