it may increase the contact wear and so decrease durability.
Between terminals of the same polarity 600 VAC 50/60 Hz for 1min
 Between current-carrying metal parts and ground 1,500 VAC 50/60 Hz for 1min  Between each terminal
and non-current-carrying metal parts 1,500 VAC 50/60 Hz for 1min 
Vibration resistance * 1 Malfunction 10 to 55 Hz, 1.5-mm double amplitude
Shock resistance
Tighten the screws to a torque of 0.08 to 0.1 N·m {0.8 to 1 kgf·cm}.
Using Micro Loads Using a model for ordinary loads to open o
r 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,
for more than 3 seconds may deteriorate the characteristics of the Switch.
• Connecting to PCB terminal Boards When using automatic soldering baths,
we recommend soldering at 260°C ±5°C within 5 seconds.
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% (λ60). (JIS C5003) The equation,
λ60=0.5×10-6/operation, indicates that the estimated malfunction rate is less than  operations with a reliability level of 60%.

 Make sure that the liquid surface of the solder does not
flow over the edge of the board. When soldering terminals manually,
Soldering • Terminal connection When soldering, make sure
that the temperature of the soldering iron tip is not higher than 300°C,
and complete the soldering within 3 seconds. Do not apply
any external force for 1 minute after soldering.
Soldering at an excessively high temperature or soldering
(at 500 VDC with insulation tester) Contact resistance (initial value) 100 mΩ max. 50 mΩ max. 30 mΩ max.
Dielectric strength
Ultra Subminiature Basic Switch with plenty of terminal variations
Incorporating a snapping mechanism made with two highly precise split springs that ensures long durability.
Using insertion molded terminals that prevents flux penetration.
In addition to self-clinching PCB, left-angled,
right-angled terminals, 2 types of soldering terminals are available.
Item 0.74 N (Low operating force) 1.47 N (General-purpose)
Permissible operating speed Pin plunger models: 1 mm to 500 mm/s, Lever models: 5 mm to 500 mm/s
Permissible operating frequency
perform soldering within 3 seconds at iron tip temperature not higher than 350°C.
Do not apply any external force for at least 1 minute after soldering. When applying solder,
keep the solder away from the case of the Switch and do not allow solder or flux to flow into the case.
Mounting Use M2 mounting screws with plane washers or spring washers to securely mount the Switch.
