Available types of ATEX / Ex safety switches
The ATEX / Ex rotary safety switch with a knob, also referred to as an emergency switch. The large, ergonomic knob with a 10 cm diameter allows for intuitive operation even when wearing gloves.
ATEX/Ex certified safety (emergency) switch with a mushroom-shaped button that is unlocked by turning. Simple press activation ensures the shortest response with any part of the body.
ATEX/Ex safety switch with a mushroom-shaped push-button that is unlocked by pulling, also called a mushroom-shaped emergency stop switch.
The ATEX/Ex mushroom safety switch with a key will work well where an emergency disconnection of the power supply may have significant consequences.
ATEX/Ex safety switch with lever designed for use in explosion hazard Zones.
Example use of ATEX / Ex safety switches
Dimensions of safety (emergency) switch housings in mm. Housings can be made of GRP (glass fiber reinforced plastic), stainless steel or aluminum. Each emergency/safety switch is equipped with cable glands according to the customer’s needs.
Advantages of the large knob in the Ex/ATEX safety switch
The use of such a switch in Zone 1, where the risk of an explosive atmosphere is constant, provides an additional layer of protection. Its construction, which is resistant to the toughest operating conditions, and compliance with Ex/ATEX standards, underline its usefulness and reliability. This switch combines high functionality with uncompromising safety, making it indispensable in industries that handle flammable substances.
Its main function is to prevent accidents by quickly cutting off power in the event of a failure or dangerous situation. The ATEX safety switch is designed to withstand extreme operating conditions and ensure reliable operation even in the most challenging environments. It can be equipped with locking systems that increase the level of protection.
Installing an ATEX safety switch is an essential part of the safety system in any industrial plant at risk of explosion, providing protection for the life and health of workers and protecting property from possible damage.
Comparison of Ex/ATEX Safety Switches with knob and mushroom head
Advantages of the Switch with a Knob with a Diameter of 10 cm:
- Ease of Use: a large knob (diameter 10 cm) makes it easier to operate the device, even when wearing thick work gloves, which is crucial in emergency situations.
- Eliminates accident: The rotating mechanism eliminates the risk of the emergency stop button being used accidentally.
Limitations of the Switch with a 10 cm Diameter Knob:
- Takes up more space: A larger knob may take up more space on the control panel, which can be a limitation in tight spaces.
- Complex movement: The knob requires complex movement, which may make it more difficult to activate in emergency situations.
Advantages of the Ex/ATEX Mushroom Safety Switch:
- Quick Activation: The mushroom shape allows for quick and easy activation with virtually any part of the body, which is crucial during sudden emergencies.
- Simplicity of use: The mushroom-shaped switch is intuitive to use, which reduces the risk of error when activating it.
Limitations of the Ex/ATEX Mushroom Safety Switch:
- Accidental Activation: Its design may lead to easier accidental activation, which may be a problem in some environments.
Conclusions from the comparison of emergency (safety) switches activated by a knob and mushroom
Choosing between an Ex/ATEX safety switch with a 10 cm diameter knob and a mushroom-head safety switch depends on specific needs and the constraints of the working environment. The knob switch provides better control and is more ergonomic, but it may be less intuitive and take up more space. On the other hand, the mushroom switch offers simplicity and quick response, but it has limitations in control and is more prone to accidental activation. The choice of the right type of switch should be dictated by the specific application and user preferences.
The switch allows for an immediate response in an emergency situation, minimizing potential hazards to human health and life and protecting property and infrastructure from damage. It is equipped with elements that enable easy and quick activation even under difficult conditions.
The design of ATEX emergency switches meets strict requirements for the working environment, ensuring their reliability and long-term operation. Their installation is mandatory in many industrial sectors. These switches are a key element of safety systems in the chemical, petrochemical, energy industries, and anywhere where production processes or the storage of substances can lead to the formation of an explosive atmosphere.
