•For soldering time, we recommend to solder within 3 s at a soldering iron temperature of under 350°C. Soldering at a temperature exceeding 350°C, soldering for more than 3 s, or repeated soldering will degrade the Switch characteristics.
Make sure that flux and liquid surface of the solder does not flow over the edge of the board when soldering. Please complete soldering at a temperature of 260°C within 5 s.
It is also recommended that you apply flux guard to the mounting surface of the Switch.

Correct Use


•Use M1.6 mounting screw with plane washers or spring washers to securely mount the Switch. Tighten the screws to a torque of 4.9 to 9.8×10-2 Nm {0.5 to 1 kgfcm}.

●Application of Operation Force to the Lever

Do not apply loads from any other directions other than operating direction of the lever as shown in the following figure. It may damage the Switch or cause malfunction.

●Mounting Plate

Use materials other than ABS or polycarbonate for the mounting plate. Since grease is used for the Switch, cracks may be caused if grease from the Switch comes in contact with such materials.

●Using Micro Loads

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). (JIS C5003) The equation, λ60=0.5×10-6/operation indicates that the estimated malfunction rate is less than 1/ 2,000,000 operations with a reliability level of 60%.
