Precautions
★Please refer to "Common Precautions" for correct use.
●Soldering
For soldering tim e , we reco mm e nd to solde r w ithi n 3 s at a
soldering iron temperature of under 350°C. Soldering at a
temperature exceeding 350°C, soldering for more than 3 s, or
repeated soldering wi ll degrade the Switch characteristics.
Make sure that flux and li quid surface of the sol der does not flow
over the edge of the board when soldering. Please complete
soldering at a temperature of 260°C within 5 s.
It is also recommended
that you apply flux
guard to the mounting
surface of the Switch.
●Mounting
Use M1.6 mountin g screw with plane was hers or spring washers
to securely mount the Switch. Tighten the screws to a torque of
4.9 to 9.8×10-2 N·m {0.5 to 1 kgf·cm}.
●Application of Operation Force to the Lever
Do not apply loads from any ot her directions other than operating
direction of the le ver as shown in the following figure.
It may damage the Switch or cause malfunction.
●Mounting Plate
Use materials other t han ABS or polycarbonat e for the mount ing
plate. Since grease is u sed for the Swi tch, it may cause crac ks if
grease from the Switch comes in contact with such materials.
●Using Micro Lo ads
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 minimu m
applicable load. This value indicates the malfunction reference
level for the reliability level of 60% (λ60). (JIS C5003)
The equation, λ60=0.5×10-6/operation indicates that the
estimated malfuncti on rate is less than operations with
a reliability level of 60%.
