Mounting 1) After mounting and wiring, the insulation distance between ground and each terminal should be confirmed as sufficient. 2) When the operation object is in the free position, force should not be applied to the actuator or to the pin plunger. Also force should be applied to the pin plunger from vertical direction to the switch. 3) In setting the movement after operation, the over-travel should be set within the range of the specified O.T. value. 4) In fastening the switch body, use the M1.4 screw, with tightening torque of not more than 0.098 N·m. 2. Soldering 1) Hand soldering should be accomplished in less than 5 seconds with an iron below 18 watts. Keep the soldering tip temperature less than 320°C. Avoid applying force to the terminals. 2) Terminal portion must not be moved within 1 minute after soldering. Also no tensile strength of lead wires should be applied to the terminals. 3) When using the angle terminal type, insert an insulation separator between the switch body and the printed circuit board (Insulation separator 0.2 to 0.4mm thick) to prevent the soldering flux from flowing under the PC board. 108 06/2009 3. Cleaning As AV4 switch is not completely sealed construction, avoid cleaning. 4. Selection of switch When specifying AV4 switches, allow ±20% to the listed operating characteristics. 5. Avoid using and keeping switches in the following conditions: • In corrosive gases • In a dusty environment • Where silicon atmosphere prevails 6. When switching low-level circuits (max. 100 mA), gold plate contact types are recommended. 7. When using the lever type, avoid applying force from the reverse and side direction of actuating.
