The Ex/ATEX switch for zones 1, 2 (gases and vapors) and 21, 22 (dusts) with a large knob of 10 cm in diameter, which allows for easy manipulation even in difficult conditions, is invaluable, especially when the user wears thick protective gloves.
The Ex industrial switch, also known as the ATEX switch, is a specialized device designed for use in explosion-prone areas. A distinctive feature of these types of switches is their ability to operate safely in environments where flammable gases, vapors, or dusts are present.
The construction of Ex switches complies with the ATEX directive. These devices must be designed to minimize the risk of ignition sources, such as electrical sparks or excessive temperature.

Advantages of the large knob in the Ex/ATEX safety switch
An industrial Ex circuit breaker, also known as an ATEX circuit breaker, is a specialized device designed for use in potentially explosive atmospheres. A characteristic feature of this type of switches is their ability to operate safely in environments where flammable gases, vapors or dust are present.
Ex/ATEX circuit breaker design
The design of Ex switches complies with the ATEX directive, a European standard that specifies requirements for devices used in potentially explosive atmospheres. These devices must be designed to minimize the risk of ignition sources, such as electrical sparks or excessive temperature. Ex industrial switches are often equipped with knobs that allow manual control over the machine or installation’s operation without the need to open the enclosure in a hazardous zone. This provides convenience and safety to operators, allowing them to manipulate the device without risking danger. Structurally, these switches are made from materials resistant to corrosion and other harmful environmental conditions typical for heavy industry.
Ex/ATEX switch for zone 1 and 2 (gases and vapors):
The ATEX switch for Zone 1 is a specially designed safety device intended for use in areas where there is a high risk of explosion due to the presence of flammable gases, vapors, or dust.
Zone 1 is classified as a place where an explosive atmosphere is likely to occur during normal operation. ATEX switches for Zone 1 must meet stringent safety standards specified in the ATEX directive of the European Union, which requires that these devices be capable of operating in these hazardous conditions without the risk of igniting the explosive atmosphere.
Ex/ATEX switch for zone 21 and 22 (dust)
The design of ATEX switches for zones 21 and 22 focuses on ensuring maximum safety by minimizing the risk of explosion. These devices often incorporate advanced technologies to prevent dust from entering the electrical mechanisms, which could become a source of ignition. Moreover, the switches are designed with ease of use and maintenance in mind, which is crucial for maintaining continuous protection in explosion-prone environments.
The ergonomics of use, resistance to mechanical damage, and long service life are features that make these switches essential in any industrial plant where Zone 21 is identified as a potential hazard. Introducing these devices significantly increases the level of safety for workers and protects infrastructure and production processes from the effects of an uncontrolled explosion.
Elimination of ignition sources in Ex ATEX circuit breakers
Ex/ATEX circuit breakers have solutions that prevent the formation of sparks or excessive heat. These devices are necessary in the chemical, petrochemical, pharmaceutical industries and wherever production processes involve the presence of flammable substances.
ATEX Certification
The Ex/ATEX switch meets the stringent safety standards set out in the ATEX directives, allowing its use in explosion-prone zones. As a result, the product is ideal for the chemical, pharmaceutical industries, or facilities processing flammable materials.
Advanced Technical Parameters
The product is characterized by high resistance to extreme temperatures, ensuring reliability in difficult working conditions. Moreover, the switch is made of materials with high corrosion resistance, which extends its lifespan even in the most demanding environments.
Durable and Safe Design
The ATEX switch has an enclosure made of glass-reinforced polyester, which not only provides excellent protection of the components but also resistance to mechanical damage. Such a solution ensures safety of use and minimizes the risk of failure.
Flexibility and Customization to Meet Customer Needs
