or both sides without the use of
any tools.
Switching current (A)
Head
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°)
Roller
Nylon rollers used for superior resistance to wear.
Seal Ring
Sealing properties improved by using a X ring and
bearing-free structure.
Conduit Opening
Models are available with a wide range of conduits.

Lever (Form Lock Structure)
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
Ground Screw
Ground screws are provided on all
models for increased safety.
