Miniature Basic Switch
Precautions
★Please refer to "Common Precautions" for correct use.
Cautions
Correct Use
●Handling
●Mounting
Do not apply excessive shock. Doing so may cause damage to
the Switch's internal components because it is designed for a
small load.
Use M3 mounting screw 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}.
●Soldering
●Mounting Direction
V
X
• Terminal connections
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.
Complete the soldering at the iron tip temperature between
250 to 350°C (60W) within 5 seconds, and do not apply any
external force for 1 minute after soldering.
Apply minimum amount of flux required. It may result in
contact failure once the flux penetrates into the internal part of
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 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).
• Connecting to Tab Terminals (#187)
When connecting to the Tab terminal, insert the receptacle of
tab #187 straight toward the terminal.
Applying excessive external force laterally may cause
deformation of terminals and may damage the housings.
(JIS C5003)
The equation, λ60=0.5×10-6/operations operation, indicates that
1
the estimated malfunction rate is less than
with a reliability level of 60%.
