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
Operation stroke
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.
Cautions
Degree of Protection
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. 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. 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.
Using Microloads
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;
Voltage (V)
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.
