Copper and chrome plating materials are available where steel is not required. The recessed panel switch now provides self-locking, on-off functionality. The illuminated switch can be either a dot-lit or ring-shaped light with a variety of colors to choose from. It is a new series and can be added to control the size of the plate. Explosion-proof electrical switches are mainly used in a variety of applications that require a safe, reliable, easy-to-break connection. Especially in the factory where the inflammable gas is likely to exist, as well as the power supply of the system; it is also used in oil and other industrial places.
To prevent rust on the explosion-proof surface, apply an oil or 204-1 displacement rust preventive oil to the explosion-proof surface. Use explosion-proof electrical equipment: First, to meet the hazardous areas classified hazardous areas to select the appropriate type of electrical explosion; Second, according to the dangerous environment may exist flammable and explosive gas / dust type to choose explosion-proof electrical equipment, the level and temperature group The third is to consider the impact of other environmental conditions on the explosion-proof performance (such as: chemical corrosion, salt spray, high temperature and humidity, sand and rain, or the impact of vibration); Fourth, to ensure the particularity of installation and maintenance; Fifth, the use of explosion-proof Certificate of conformity and corresponding certified products of the country. Environmental requirements for explosion-proof electrical equipment applications: Explosive risk environments/workplaces with flammable and explosive gases/vapours. Explosive atmosphere / workplace with flammable dust. The environment/workplace where flammable and explosive gases/vapours and flammable dust are present at the same time is common in solid state chemical products workshops and their transportation, packaging, weighing and coating process installations.
Explosion-proof electrical switches are generally applied to the coal industry, petroleum, power, metallurgy, railways, ships, navigation companies and other enterprises, and therefore require high wear and corrosion resistance and destructive resistance, explosion-proof electrical switches with these properties. Explosion-proof electrical switch front and rear panel fixed switch has three kinds of shapes: convex, circular and horizontal. According to the needs of the human environment, the electronic and natural environment, there are many options for the switch function, and the board installation can meet the IP and IPE8 standards.
