Precautions

★ Please refer to "Basic Switches Common Precautions" for correct use.

●Soldering

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.

When soldering terminals manually, complete the soldering at

the iron tip temperature between 350 to 400°C within 3 seconds,

and do not apply any external force for 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 M2.3 mounting screw with plane washers or spring washers

to securely mount the Switch. Tighten the screws to a torque of

0.23 to 0.26 N·m {2.3 to 2.7 kgf·cm}.

●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% (

(JIS C5003)

The equation,

estimated malfunction rate is less than

operations with

a reliability level of 60%.
