Hazardous-Location Selector Switches

Available6 products

Hazardous-location selector switches are for environments where the possibility of flammable gases, vapors, or liquids, ignitable fibers or particles, or combustible dust may exist under normal and abnormal conditions. They have location ratings that classify their suitable operating environment and must be paired with similarly-rated hazardous-location devices to be compliant with safety standards. Selector switches rotate to control connected machines, motors, or industrial systems. They support multiple circuits or functions and have labels or marks that help identify their set position.
