D4A-
@N
83
Note: Switches with indicators are factory-set to light when the switch is not operated, but the setting can be changed to light for operation (dotted
lines).
Nomenclature
DPDT Double-break
Note: 1. NBR is used in rubber components.
2. Fluoro-rubber sealed types use fluoro-rubber.
3. 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.
Item
Without indicator
With neon lamp indicator (See note.)
With LED indicator (See note.)

Conduit Opening
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
Sealed Gasket
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.
The copper-alloy bearings ensure long life ex-
pectancy.
The plug-in type receptacle provides adequate
space for wiring.
G 1/2 conduit threads featuring high sealing
property are used. (Consult your OMRON
representative for details on SC connectors).
A terminal box with 1/2-14NPT conduit threads
is also available on request.
The employed full-cover method
prevents the gasket from direct
exposure to oil or water spray.
A Phillips screw is used to secure the switch
housing for ease of use, and features a meas-
ure to prevent the screw from coming off.
