• Manufacturer Part Number: D2SW
• Description: Snap Action Switch
• Manufacturer: Omron Corporation

Precautions
■ Mounting
Use two M2.3 mounting screws with spring washers to mount the
switch. Tighten the screws to a torque of 0.23 to 0.26 N • m (2.3 to
2.7 kgf • cm)
Mounting holes
When soldering a lead wire to a terminal of the D2SW, use a solder-
ing iron with a maximum capacity of 60 W and do not take more than
5 seconds to solder the lead wire, otherwise the characteristics of the
D2SW may be altered.
Make sure that there is no icing when using the D2SW at low ambi-
ent temperatures.
■ Operations
Make sure that the switching object is perfectly separated from the
actuator when the switch is not operated and the actuator is pressed
appropriately by the switching object when the switch is operated.
The switch should be set so that its stroke will be within the rated OT
when the switch is operated.
Install the switching object so that its moving direction is the same as
that of the actuator.
Handle D2SW models with pin plungers with care so that the sealing
rubber parts around the pin plungers will not be damaged.

■ Enclosure Ratings
The D2SW was tested under water and passed the following water-
tightness test, which however, does not mean that the D2SW can be
used in the water. JIS C0929 (rules for testing the watertightness of
electrical devices and materials), class 7 (watertightness test). Refer
to the following illustration for the test method.
IEC Publication 529, class IP67. Refer to the following illustration for
the test method.
Note: The object to be tested is left in the water for 30 minutes on con-
dition that the distance between the surface of the water and
the top of the object be 15 cm minimum, and the distance be-
tween the surface of the water and the bottom of the object be
1 m minimum.
