EXPLOSION PROOF SWITCHES
Notes:
Add the letter "A" to listings with side mounting holes tapped 5/16 (8).
Example: 11CX2A
Add the letter "B" to listings with thru mounting holes tapped 3/8-24 (4).
Example: 11CX2B
Add the letter "C" to listings for low temperature (-40 °C/°F) applications.
Example: 11CX2C
Add "D01" to specify a "direct-couple" listing with 3/8 in. dia by 3/4 in. long
flatted shaft.
Example: 11CX2-D01
Add the letter "E" to listings for European Atex approvals.
Example: 11CX2E
For Replacement Basic Switch Assemblies, change the first number in the

Bronze housing for use in corrosive
environments
80CX switches have rugged bronze housings which are resistant to salt water
and other corrosive environments. They comply with the NEMA 4X
requirement for protection against corrosion, in addition to NEMA enclosure
standards met by other CX switches. O-ring seals make the enclosure weather-
proof, but are outside of required flame paths, maintaining explosion-proof
requirements.
