Head
With the Roller Lever and Side Plunger Switches, the
direction of the switch head can be varied to any of the four
directions by loosing the roller lever switch screws at the
four corners of the head.
The Roller Lever Switch
employs a system which
allows selection of the
operation of only one side
(left or right) or both sides
without use of any tools.
Bearings
The copper-alloy bearings ensure long life
expectancy.
Receptacle
The plug-in type receptacle provides adequate
space for wiring.
Conduit Opening *1, *2
G 1/2 conduit threads featuring high sealing
property are used. (Refer to Limit Switch
Connectors for details on SC connectors).
A terminal box with 1/2-14NPT conduit threads
is also available on request.

Note: 1. NBR is used in rubber components.
*1. A Receptacle and Terminal Box with 1/2-14NPT conduit threads are also available for the North America market.
*2. The conduit thread indication has been changed from “PF1/2” to “G1/2” accompanying the JIS B 0202 revision.
This changes applies only to the indication; thread sizes and pitches have not been affected.

2. For Roller Levers, there is some lever play in the free position (about 2 mm), but this is due to the structure of the head and does not interfere with performance.

Roller
The roller actuator is made of hardened
stainless steel and excels in resistance to
wear.
Lever
With the Roller Lever Switch, the lever can
be installed anywhere in a 360° range (180°
if the lever is reversed and attached to
the shaft).
Oil Seal
Improved sealing property is ensured with a
double-seal construction (a oil seal plus an
X-ring seal).
Switch Box
Boasts long life expectancy (50 million
mechanical operations or more with the
2-pole Double-break Switches and
30 million mechanical operations or more
with the DPDT Double-break Switches).
Ground Terminal Screw
A ground terminal is provided to enhance
safety.
Switch Box Screw
A Phillips screw is used to secure the switch
housing for ease of use, and features a
measure to prevent the screw from coming off.
