Conduit Opening
Roller
Ground Screw
Ground screws are provided on all
models for increased safety.
Lever (Form Lock Structure)
Seal Ring
Can be connected in any of four directions (except for
Roller Plunger Models, which can be connected at either
of 2 directions that differ by 90°)
The roller lever switch employs a
system which allows
selection of operation on only one
side (left or right)
or both sides without the use of
any tools.
G1/2 or M20
Nylon rollers used for superior resistance to wear.
The lever has an operating position indication plate
and grooves that mate every 90° to prevent slipping
between the rotary axis and lever.
Built-in Switch
Direct opening mechanism used for NC contact to
separate contact for faults, such as contact welding.
The heights of the NC and NO terminals are different
to enable easier wiring.
Cover
Sealing properties improved by using a X ring and
b
earing-free structure.
