Application and Classification of Explosion-Proof Switches


Explosion-proof switch , as the name implies, is a switch that can be used in harsh and dangerous explosive environments. Explosion-proof switches are mainly used in applications that require a safe, reliable, and easy-to-disconnect connection. They are especially used in machine equipment and system power supply situations in manufacturing plants where flammable gases may exist; also used in the petrochemical industry; including mills, granaries, paint or ink factories, wood processing plants, cement plants, shipping, and sewage treatment.


 


  Explosion-proof switches are also suitable for external electrical equipment, such as motors, pumps, lighting equipment, and process control devices used in hazardous plants and factories, or in explosive environments that may cause flammable gases, vapors, mist gases, or flammable dust.


 


  Reversing Switch


 


  The housing is made of high-strength aluminum alloy through one-time die-casting, and the surface is cleaned by high-speed shot blasting and then electrostatically sprayed with high-pressure plastic powder. The shell structure is compact and reasonable, with high material density and good strength, excellent explosion-proof performance, strong adhesion of surface plastic powder, good anti-corrosion ability, smooth surface, and beautiful appearance;


 


  It is equipped with a reversing switch inside, used in electrical circuits with current below 100A, as a power supply introduction switch, and can control motor start, stop, reversing, etc.


 


  Good dustproof and waterproof performance, reliable.


 


  Pull Switch


 


  This machine adopts precision die-cast aluminum alloy housing, high strength, light weight; the shell protection level reaches IP67, can work in harsh environments for a long time; the machine uses imported components, large contact capacity, sensitive and reliable operation.


 


  Lighting Switch


 


  Widely used in hazardous environments such as oil extraction, refining, chemical, military, and offshore oil platforms, oil tankers, etc.


 


  Limit Switch


 


  The explosion-proof limit switch housing is made of high-strength aluminum alloy through one-time die-casting, and the surface is cleaned by high-speed shot blasting and then electrostatically sprayed with high-pressure plastic powder. The shell structure is compact and reasonable, with high material density and good strength, excellent explosion-proof performance, strong adhesion of surface plastic powder, good anti-corrosion ability, smooth surface, and beautiful appearance;
