Sealed Miniature Basic Switch
Cautions
● Degree of Protection
Do not use the Switch underwater.
The Switch was tested and found to meet the conditions
necessary to meet the following standard, however, the test
Correct Use
● Mounting
Use M3 mounting screw with plane washers or spring washers to
securely mount the Switch. Tighten the screws to a torque of
0.39 to 0.59 N·m {4 to 6 kgf·cm}.
The equation, λ 60 =0.5×10 -6 /operations indicates that the
estimated malfunction rate is less than 2,000,000 operations
checks for water intrusion after immersion for a specified time
period, not for switching operation underwater.
JIS C0920:
Degrees of protection provided by enclosures of electrical
apparatus (IP Code)
IEC 60529:
Degrees of protection provided by enclosures (IP Code)
Degree of protection: IP67
(check water intrusion after immersion
for 30 min submerged 1 m underwater)
● Protection Against Chemicals
Prevent the Switch from coming into contact with oil or
chemicals.
Otherwise, damage to or deterioration of Switch materials may
result.
● Soldering
? Connecting to Solder Terminals
When soldering the lead wire to the terminal, first insert the
lead wire conductor through the terminal hole and then
conduct soldering.
Complete the soldering at the iron tip temperature between
350 to 400°C within 3 seconds, and do not apply any external
force for 1 minute after soldering. Soldering at a excessively
high temperature or soldering for more than 3 s may
deteriorate the characteristics of the Switch.
● Operating Body
With the pin plunger models, set
the Switch so that the plunger can
be pushed in 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.
● Handling
Handle the Switch carefully so as not to break the sealing
rubber.
● Using Micro Loads
Using a model for ordinary loads to open or close the contact of
a micro load circuit may result in faulty contact. Use models that
operate in the following range. However, even when using micro
load models within the following operating range, if inrush
current occurs when the contact is opened or closed, it may
increase the contact wear and so decrease durability. Therefore,
insert a contact protection circuit where necessary. The N-level
reference value applies for the minimum applicable load. This
value indicates the malfunction reference level for the reliability
level of 60% ( λ 60 ).
