The foot switch is a type of switch. It is mainly used to operate the circuit by stepping on the foot. Can it also control the size of the current? Most of us have never touched the foot switch. Because the foot switch is mainly used in medical equipment and stamping equipment. Next, Zhejiang Shuyi introduced the principle of the foot switch.
The foot switch is a switch that controls the on-off of the circuit by stepping on or stepping on it. It is used in the control circuit that cannot be touched by both hands to replace the hands to achieve the purpose of operation. A simple foot switch is actually a built-in travel switch. When the foot pedal gives a signal, the switch is executed. But in the field of welding, the function of the foot switch also plays the role of controlling the output current.
This type of foot switch can also be divided into two categories: one, mechanical foot switch; two, inductive foot switch. The mechanical foot switch is a traditional rack and pinion drive, and the induction type is based on the principle of electromagnetic induction. Foot switch HRF-M series, HRF-H series has H type (15A/250V opening and closing capacity) and M type (10A/250V opening and closing capacity) in terms of structure and function. Steel plate, aluminum alloy.
The above is the relevant content introduced by Zhejiang Shuyi about the principle of the foot switch. I believe that after reading this article, you will have a better understanding of the foot switch. Because the foot switch mainly controls the circuit, it is still necessary to pay attention to the safe use of electricity, and pay attention to fireproof and waterproof around the use.
