Precautions
★Please
refer to "Common Precautions" for correct use.
Cautions
●Soldering
For soldering time, we recommend to solder within 3 seconds at
a soldering iron temperature of less than 350°C. When soldering
exceeds this temperature and time, or repeated soldering will
degrade the Switch characteristics.
Make sure that flux and liquid
surface of the solder do not flow
Switch mounti
surface
over the edge of the board when
soldering. Please complete
soldering at a temperature of
260°C within 5 seconds.
It is also recommended that you apply flux guard to the mounting
surface of the Switch.
●Mounting
Plate
Use materials other than ABS or polycarbonate for the mounting
plate. Since grease is used for the Switch, cracks may occur if
grease from the Switch comes in contact with such materials.
●Using
Micro Loads
It is recommended to use the Switch in the operation range
shown below. 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 minimum
applicable load is the N-level reference value. This value
indicates the malfunction reference level for the reliability level of
60% (λ
60
). (JIS C5003)
The equation,
λ
60
=0.5×10

/operation, indicates that the
1
estimated malfunction rate is less than
2,000,000
operations with
a reliability level of 60%.
Voltage (V)
Correct Use
●Mounting
Use M2 mounting screw with plane washers or spring washers to
mount the Switch. Tighten the screws to a torque of 4.9 to
9.8×10

●Application
of Operation Force to the Actuator
Do not apply operation forces other than in the operating
direction of the lever as shown in the following figure.
It may damage the Switch or
cause malfunction.
