Precautions
Refer to General Information.
■Cautions
Terminal Connection
When soldering a lead wire to the terminal, first insert the lead
wire conductor into the terminal hole and then perform soldering.
Make sure that the capacity of the soldering iron is 30 W maxi-
mum and that the temperature of the soldering iron tip is approxi-
mately 300°C. (350°C maximum.) Complete the soldering within
3 s.
Using a switch with improper soldering may result in abnormal
heating, possibly resulting in burn.
Applying a soldering iron for more than 3 s or using one that is
rated at more than 30 W may deteriorate the switch characteris-
tics.
When using automatic soldering baths, we recommend soldering
at 260±5°C within 5 seconds. Make sure that the liquid surface of
the solder does not flow over the edge of the board.
■Correct Use
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 M2 mounting screws with plane washers or spring washers
to securely mount the Switch. Tighten the screws to a torque of
0.08 to 0.1 N·m {0.8 to 1 kgf·cm}.
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.
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 = 0.5×10–6/operations
indicates that the estimated malfunction rate is less than 1/
2,000,000 operations with a reliability level of 60%.
