Precautions
Be sure to read the precautions and information common to all Snap Action and Detection Switches, contained in the Technical User’s Guide,
“Snap Action Switches, Technical Information” for correct use.
■ Correct Use
■ Cautions
Operation stroke
Degree of Protection
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 D2SW was tested under water and passed the following watertightness 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.
The switch should be set so that its stroke will be within the rated OT
when the switch is operated.
IEC Publication 529, class IP67. Refer to the following illustration for
the test method.
Handling
Install the switching object so that its moving direction is the same as
that of the actuator. With the pin plunger models, set the switch so
that the plunger can be actuated from directly above. Since the
plunger is covered with a rubber cap, applying a force from lateral
directions may cause damage to the plunger or reduction in the
sealing capability.
Correct
Incorrect
Incorrect
Note: The object to be tested is left in the water for 30 minutes on condition that the distance between the surface of the water and
the top of the object be 15 cm minimum, and the distance between the surface of the water and the bottom of the object be
1 m minimum.
Protection Against Chemicals
Handle D2SW models with pin plungers with care so that the sealing
rubber parts around the pin plungers will not be damaged.
Make sure that there is no icing when using the D2SW at low
ambient temperatures.
Using Microloads
Voltage (V)
Using a model for ordinary loads to switch microloads may result in
faulty operation. Instead, use the models that are designed for
microloads and that operate in the following range;
Operating range
for micro load
models D2SW-01
Operating
range for
general-load
models
D2SW-3
Inoperable
range
Current (mA)
However, even when using microload models within the operating
range shown above, if inrush current or inductive voltage spikes
occur when the contact is opened or closed, then contact wear may
increase and so decrease the service life. Therefore, insert a contact
protection circuit where necessary.
200
Sealed Snap Action Switch
D2SW
Prevent the switch from coming into contact with oil and chemicals.
Otherwise, damage and deterioration to the switch materials may
occur.
Soldering
When soldering a lead wire to a terminal of the D2SW, use a soldering iron with a maximum capacity of 30 W and do not take more than
5 seconds to solder the lead wire, otherwise the characteristics of the
D2SW may be altered.

Certain Precautions on Specifications and Use
1. Suitability for Use. Seller shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the Product in
Buyer's application or use of the Product. At Buyer's request, Seller will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not
sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use.
Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer's application, product or system. Buyer
shall take application responsibility in all cases but the following is a nonexhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety
equipment, and installations subject to separate industry or government
regulations.
(iii) Use in consumer products or any use in significant quantities.
(iv) Systems, machines and equipment that could present a risk to life or
property. Please know and observe all prohibitions of use applicable to this
product.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE SYSTEM
AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT
THE OMRON PRODUCT IS PROPERLY RATED AND INSTALLED FOR THE
INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Seller shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
3. Performance Data. Performance data given in this publication is provided as
a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Seller's test conditions, and the users must
correlate it to actual application requirements. Actual performance is subject to
Seller's Warranty and Limitations of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed,
