Precautions ★Please refer to "Common Precautions" for correct use. ●Mounting Plate Cautions Use materials other than ABS or polycarbonate for the mounting plate. Since grease is used for the Switch, cracks may occur if ●Soldering grease from the Switch comes in contact with such materials. For soldering time, we recommend to solder within 3 seconds at ●Using Micro Loads a soldering iron temperature of less than 350°C. When soldering It is recommended to use the Switch in the operation range exceeds this temperature and time, or repeated soldering will shown below. However, even when using micro load models degrade the Switch characteristics. within the following operating range, if inrush current occurs Make sure that flux and liquid when the contact is opened or closed, it may increase the surface of the solder do not flow Switch mounti surface contact wear and so decrease durability. Therefore, insert a over the edge of the board when contact protection circuit where necessary. The minimum soldering. Please complete applicable load is the N-level reference value. This value soldering at a temperature of indicates the malfunction reference level for the reliability level of 260°C within 5 seconds. 60% (λ60). (JIS C5003) It is also recommended that you apply flux guard to the mounting -6 The equation, λ60=0.5×10 /operation, indicates that the surface of the Switch. 1 estimated malfunction rate is less than operations with 2,000,000 Correct Use a reliability level of 60%. ●Mounting Use M2 mounting screw with plane washers or spring washers to 0.16 mA 100 mA 30 mount the Switch. Tighten the screws to a torque of 4.9 to -2 9.8×10 N • m {0.5 to 1kgf • cm}. 24 ●Application of Operation Force to the Actuator Do not apply operation forces other than in the operating Operating range direction of the lever as shown in the following figure.
