Cautions Correct Use ●Soldering ●Mounting (cid:129)Terminal connections Use M1.4 mounting screw with plane washers or spring washers When soldering terminals manually, perform soldering within 3 to securely mount the Switch. Tighten the screws to a torque of seconds at iron tip temperature no higher than 300°C. Do not 0.08 to 0.1 N·m {0.8 to 1 kgf·cm}. apply any external force for 1 minute after soldering. When applying solder, keep the solder away from the case of the ●Operation Switch and do not allow solder or flux to flow into the case. (cid:129)Do not apply a force more than two times the rated operating It is recommended that you apply flux guard to the mounting force to the actuator and leaf lever. surface of the Switch. (cid:129)Provide an amount of OT that equals or exceeds the standard. (cid:129)Do not change the operating position by modifying the actuator. (cid:129)Do not use the Switch in an application where the operating speed is extremely slow or the actuator is set in the midpoint between the free position and operating position. (cid:129)Mount the pin plunger so that the operating force is applied in perpendicular alignment with the stroke of the actuator. (cid:129)Do not apply a shock to the actuator, otherwise, the Switch may be damaged. (cid:129)Do not apply excessive force to the actuator of the Leaf Lever Switch in the operating, releasing, and horizontal directions. 3
