Precautions
★Please refer to "Common Precautions" for correct use.
Cautions
●Soldering
●Mounting Plate
For soldering time, we recommend to solder within 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 will degrade the Switch characteristics.
Make sure that flux and liquid surface of the solder does not flow
over the edge of the board when soldering. Please complete
soldering a t a temperature of 260°C within 5 s.
It is also recommended
that you apply flux
Switch mounting surface
guard to the mounting
surface of the Switch.
Use materials other than ABS or polycarbonate for the mounting
plate. Since grease is used for the Switch, it may cause cracks if
grease from the Switch comes in contact with such materials.
Correct Use
●Mounting
Use M1.6 mounting screw with plane washers 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
●Using Micro Loads
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% (λ60). (JIS C5003)
The equation, λ60=0.5×10-6/operation indicates that the
1
estimated malfunction rate is less than 2,000,000 operations with
a reliability level of 60%.
