Nomenclature
Head
With roller lever switches, the direction of the switch head
can be adjusted to any of the four directions by loosening
the roller lever switch screws at the four corners of the head.
Safety-oriented Lever Setting
Grooves which engage the lever every 90°are cut in the
operation indicator disk to prevent the lever from slipping
against the rotary shaft.
Cover
The cover, with a hinge on its lower part, can be opened by
removing the screw of the cover, which ensures ease of
maintenance and wiring.
Built-in Switch
Has a positive opening mechanism separating the con-
tacts when the contacts are welded.
Conduit
Wide switch variations.
Pg13.5: 1-conduit, 2-conduit models
G1/2: 1-conduit, 2-conduit models
1/2-14NPT: 1-conduit models
Reset Head
The direction of the reset head can be adjusted to any of
the four directions.
Note: The D4D-jR uses NBR.
