Max. Auto soldering sec. Max. The above-stated soldering conditions shall apply only to switches with straight terminals. Auto soldering is not possible with right-angle terminals. Switches with right-angle terminals should be soldered manually according to the conditions specified in () above. When putting the switches through an aging process after they were soldered onto the printing board or after installed into a complete end product, be sure to remove the buttons ofthe switches.,. Mounting Do not bend the terminals before mounting the switch on the PC board. After mounting the switch, do not place the device in such a way that the device weight will be applied on to the actuator of the switch. For switches with straight terminals, solder the switch on the PC board after fixing the switch on the panel with a nut. 3. Flux Cleaning Solvent : Fluorine or Alcohol type. 8A/B/C/D/E/F/J/S series are not washable. To wash the PC board, clean the soldering surface of the PC board with a brush so that the switch is not exposed to the cleaning solution. Packaging Speci cation Perforated Plastic Bag 5 pcs/pack
