Precautions

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

●Soldering

• Complete the soldering at the iron tip temperature below

350°C within 5 seconds, and do not apply any external force

for 1 minute after soldering. Soldering at an excessively high

temperature or soldering for more than 5 seconds may

deteriorate the characteristics of the Switch.

• Be sure to apply only the minimum required amount of flux.

Switch may have contact failures if flux intrudes into the

interior of the Switch.

• If the PCB terminal models are soldered in the solder bath, flux

will permeate inside the Switch and cause contact failure.

Therefore, manually solder the PCB terminal.

●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}.

• Mount the Switch onto a flat surface. Mounting on an uneven

surface may cause deformation of the Switch, resulting in

faulty operation or breakage in the housing.

●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%.
