Cautions
●Soldering
For soldering time, we recommend to solder within 3 seconds at a soldering iron temperature of less than 350°C. When soldering exceeds this temperature and time, or repeated soldering will degrade the Switch characteristics. Make sure that flux and liquid surface of the solder do not flow over the edge of the board when soldering. Please complete soldering at a temperature of 260°C within 5 seconds. It is also recommended that you apply flux guard to the mounting surface of the Switch.
Correct Use
●Mounting
Use M2 mounting screw with plane washers or spring washers to mount the Switch. Tighten the screws to a torque of 4.9 to 9.8×10-2N m {0.5 to 1kgf cm}.
●Application of Operation Force to the Actuator
Do not apply operation forces other than in the 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
It is recommended to use the Switch in the operation range shown below. 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% (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%.
