J CONTACT FORM (EN50013)
J POSITIVE CONTACT OPENING MECHANISM
1NO/1NC Contact (Snap-action)
If metal deposition between mating contacts occurs on the NC contact side, they can be pulled apart by the shearing force and tensile
force generated when part B of the safety cam or plunger engages part A of the movable contact blade. When the safety cam or plunger
is moved in the direction of the arrow, the Limit Switch releases.
1. When metal deposition occurs.
Head
With roller lever models, the direction of the switch head can
be varied to any of the four directions by loosening the roller
lever switch screws at the four corners of the head.
The roller lever switch em-
ploys a system which allows
selection of operation on
only one side (left or right)
or both sides without the
use of any tools.
Conduit Opening
Available in three different types of conduit threads:
Pg 13.5, G1/2 or 1/2-14NPT

Safety-Oriented Lever Setting
Grooves which engage the lever every 90° are cut in the
operating position indicator plate to prevent the lever from
slipping against the rotary shaft.
Equipped with Operating Position Indicator Plate
An optimum overtravel (OT) value may be secured by
setting a desired OT value with a projection.
Shearing Force Contact Separating Mechanism
(NC Contact Section Only)
Should any abnormality occur in the contact area, the
contacts are positively pulled apart from each other by
shearing force.
Ground Terminal Screw
A ground terminal is provided to improve safety.
