Roller Plunger Models, which can be connected at either
of 2 directions that differ by 90°)
The roller lever switch employs a

Roller
selection of operation on only one
side (left or right)
Nylon rollers used for superior resistance to wear.
or both sides without the use of
any tools.
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.
Seal Ring
Sealing properties improved by using a X ring and
bearing-free structure.
The operating position indicator plate
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.
