Precautions
Refer to General Information.
■
Handling
Be careful not to drop the Switch. Doing so may cause damage to
the Switch’s internal components because it is designed for a
small load.
■
Mounting
Use M3 mounting screws with plane washers or spring washers
to securely mount the Switch. Tighten the screws to a torque of
0.39 to 0.59 N·m {4 to 6 kgf·cm}.
Mounting Direction
For a Switch with an actuator, mount the Switch in a direction
where the actuator weight will not be applied to the Switch.
Since the Switch is designed for a small load, its resetting force is
small. Therefore, resetting failure may occur if unnecessary load
is applied to the Switch.

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%.
