Hazardous Location Switches – Allen-Bradley
Hazardous Location Switches from Allen-Bradley are industrial control devices specifically designed for use in environments with explosive gases, dust, or fibers. These switches provide reliable control, safety, and signaling in harsh and potentially dangerous industrial locations, ensuring compliance with international safety standards such as ATEX, IECEx, UL, and CSA.
What Are Hazardous Location Switches?
Hazardous Location Switches are engineered to operate safely in Class I, II, and III hazardous areas. They are used to control machinery, start/stop processes, and provide operator interfaces in environments where standard industrial switches may pose ignition risks. Allen-Bradley hazardous location switches integrate with PLCs, PACs, motor starters, and other industrial automation systems to provide safe and reliable operation.
Allen-Bradley Hazardous Location Switch Product Families
- Explosion-Proof Push Buttons – Rugged push buttons designed for use in flammable or explosive atmospheres.
- Selector Switches – Rotary and key-operated switches providing safe mode selection in hazardous locations.
- Emergency Stop Devices – Safety-rated E-Stop switches engineered for quick shutdown in dangerous conditions.
- Safety Interlock Switches – Switches that secure access points, doors, or machinery to prevent unsafe operation in hazardous areas.
