* May be modified in field to suit application requirements.

Note: Levers are ordered separately (see pages 69- 71 for details)

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 listing to “9”.

Example: 11CX2 becomes 91CX2

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.
