The EX Series features the smallest UL listed housings available for use in
hazardous locations. Flame paths within the housing cool exploding gases
below the kindling temperature before they reach the explosive gases
surrounding the housing.
Options available include single or double conduit connection.
These switches are not sealed against liquids and should not be used where
there will be liquid splash. If a weather sealed explosion proof switch is
required please select from the CX or LSX/BX series.
