Nomenclature
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.
Operating Position Mark

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.
Contact Material
Ag alloy
