Precautions

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

●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 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. Make sure that the

liquid surface of the solder does not flow over the edge of the

board.

When soldering terminals manually, 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. 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 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

minimum applicable load is the N-level reference value. 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%.
