LEVER-TO-BUSHING SEAL OPTION
A splash type lever-to-bushing seal can
be provided to help prevent the entrance
of moisture and dust behind the panel, or
into the contact area. To specify 2-posi-
tion switches with lever-to-bushing seals,
change the 23AT catalog listing prefix to
32AT. Example:
32AT1
is a sealed 23AT1.
Convert 3-position catalog listings by
changing the 13AT prefix to 31AT. Exam-
ple:
31AT2-T
is a sealed 13AT2-T.
