Safety Precautions Refer to Safety Precautions for All Pushbutton Switches/Indicators. Precautions for Correct Use Calculation Example for Limiting Resistance • Always make sure that the power is turned OFF before mounting, removing, or wiring the Switch, or performing maintenance. Electric shock or fire may occur. • Do not tighten the mounting ring excessively using pliers or a similar tool. Excessive tightening may damage the mounting ring. (Tightening torque: 0.20 to 0.29 N·m) Wiring • When wiring, use wires of a size appropriate for the applied voltage and carry current. Perform soldering correctly under the conditions given below. Using the Switch with the wires soldered incorrectly may cause the terminals to become abnormally hot and cause a fire. 1. Hand soldering: Soldering iron tip temperature: 350°C max. within 3 seconds. 2. Dip soldering: At 350°C within 3 seconds. Wait for one minute after soldering before exerting any external force on the solder. • Use a non-corrosive rosin liquid for the flux. • Perform wiring so that the wire sheaths do not come into contact with the Switch. If this is unavoidable, use wires that can withstand temperatures of 100°C min. After wiring to the Switch has been completed, ensure an appropriate insulation distance. LED • The polarity of the LED is indicated on the back of the Switch. Wire the LED correctly according to the polarity. • The built-in LED does not have a limiting resistor. Connect a limiting resistor. • Make sure that the limiting resistor satisfies the characteristics of the built-in LED. The forward current of the built-in LED must be 8 mA minimum. • The resistance can be calculated by using the following expression. E-VF (Ω) E : Operating voltage (V) R=-----------IF VF : LED forward voltage (V) IF : LED forward current (A) LED lamp illuminating color: Red E = 24V IF = 20mA Ta = 25°C The VF-IF characteristics (for red) on page 4 yield the following: VF = 1.7 V when IF = 20 mA. Therefore, inserting the values into the formula above (R = E − VF/IF(Ω)): R = 24 (V) − 1.7 (V)/0.02 (A) ≅ 1100 (Ω). The recommended resistance is 1.1 kΩ at 1 W (2 × IF2R). Note: Approximately twice this value is appropriate to provide a margin in the capacity of the resistor. A 3 D Operating Environment • Ensure that dust, metal powder, or oil do not enter the interior of the Switch. Using Microloads • Using a standard load switch for opening and closing a microload circuit may cause wear on the contacts. Use the switch within the operating range. (Refer to the diagram below.) Even when using microload models within the operating range shown below, if inrush current occurs when the contact is opened or closed, it may cause the contact surface to become rough, and so decrease life expectancy. 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% (λ 60) (conforming to JIS C5003). The equation, λ 60 = 0.5 x 10−6/times indicates that the estimated malfunction rate is less than 1/2,000,000 with a reliability level of 60%.

Application Mounting and Replacing the Pushbutton Socket Mounting (1) Mounting Direction for the Pushbutton and Switch Curved claw Projection (Pushbutton) (Switch) A 3 D • Align the curved claw on the outside of the protruding part of the Pushbutton with the projection on the upper part of the Switch and insert. • Apply a pressure between 9.8 and 24.5 N. • If the terminals of the LED lamp become bent, it may be impossible to fit them into the LED lamp terminal holes. Ensure that the terminals are straight when they are inserted. Be sure to insert the lamp terminals for round models (A3DT or M2DT) with the correct orientation. Inserting the terminals with the reverse orientation will result in damage. (2) Removing the Pushbutton Recessed portions • Hold the recessed portions on the cap of the Pushbutton and pull. • Do not use tools such as pliers to remove the Pushbutton as this may damage the cap. Panel Mounting Using the Mounting Nut • Insert the Switch from the front of the panel. Mount the mounting nut from the terminal end of the Switch and tighten it. • Tighten the nut to a torque 0.20 to 0.29 N·m. • If soldering is used, mount the mounting nut first. Lead wires and mounds of solder may make it impossible to mount the nut after soldering. Mounting nut Panel 9 • After securing the Switch to the panel using the mounting nut, insert the Socket into the Switch. • When inserting the Socket, align the positioning groove of the Socket with the projecting part of the Switch.
