What is the principle of the foot switch?
Foot switch is a kind of switch that controls the circuit through foot stepping or stepping. It is used in the control circuit that cannot be touched by both hands to replace both hands to achieve the purpose of operation. The simple foot switch is actually a built-in trip switch, when the foot gives a signal, the switch is executed. However, the function of the foot switch in the welding field also plays a role in controlling the output current.
What are the types of foot switches?
There are two kinds of mechanical foot switch and inductive foot switch. Among them, the mechanical foot switch is the traditional rack and pinion transmission, and the induction type is through the principle of electromagnetic induction. Foot switch HRF-M series, HRF-H series, from the structure and function to distinguish H type (15A/250V opening and closing capacity) and M type (10A/250V opening and closing capacity), from the material to distinguish with flame retardant engineering plastics, steel plate, aluminum alloy.
What are the characteristics of foot switch?
1, surface spray coating, impact resistance, wear resistance, high temperature (180 degrees) performance is excellent.
2, the cable is equipped with electric cable head, so the waterproof, oil, impact effect is outstanding.
3. The cable lead length is 2 meters in standard configuration, and the M type is 0.5 square. H type 0.75 square.
4. The built-in micro switch has been certified by UL, VDE, TUV, CE and CCC.
5, built-in micro switch contact plated 24 karat gold treatment.
6, "H" type to achieve IP65 protection grade.
7, all models through the CE certification, China product safety CCC certification.
What are the notes of foot switch?
1, according to the nature of the load and the different current value, please pay attention to the rated load of the product.
2. Please pay attention to the short circuit and open circuit of internal wiring when handling and moving.
3, use in a large amount of water, oil, dust and other places, please pay attention to the protection level of the product.
4, weight and impact is the direct cause of product damage, please be careful when using.
