Precautions
Refer to General Information.
■
Terminal Connection
When soldering the lead wire to the terminal, first bind the lead
wire to the terminal and then apply the solder to the terminal.
Complete soldering within 5 s at a soldering iron temperature of
260°C. Soldering at a temperature exceeding 260°C, soldering for
more than 5 s, or repeated soldering will degrade the Switch char-
acteristics.
When using automatic baths, we recommend soldering at 260±5°C
within 5 seconds.
Make sure that liquid surface of the solder does not flow over the
edge of the board.
It is also recommended that you apply flux guard to the mounting
surface of the Switch.
■
Mounting
Turn OFF the power supply before mounting or removing the
Switch, wiring, or performing maintenance or inspection. Failure
to do so may result in electric shock or burning.
Use M1.6 mounting screws with plane washers or spring washers
to securely mount the Switch. Tighten the screws to a torque of
4.9 to 9.8×10
Mount the Switch onto a flat surface. Mounting on an uneven sur-
face may cause deformation of the Switch, resulting in faulty oper-
ation or breakage in the housing.
Application of Operation Force to the Lever
Apply operation forces to the pushbutton in its operating direction.
Applying operating force to the pushbutton in any other directions
will damage the Switch or cause malfunction.
Mounting Plate
Use materials other than ABS or polycarbonate for the mounting
plate. Since grease is used for the Switch, cracks may be caused
if grease from the Switch comes in contact with such materials.

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 operating range shown below, if inrush
current occurs when the contact is opened or closed, it may
increase 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). The equation, λ 60 = 0.5×10
indicates that the estimated malfunction rate is less than 1/
2,000,000 operations with a reliability level of 60%.
