For Stoppers other than those for the A7BS-20-S, refer to pages 5 to
11 of the Selection Guide as well as the ordering information on
page 15. All manufactured Switches have their ranges factory-set
before shipment.
Soldering
Note the following points when soldering printed circuit boards:
Automatic Soldering
After coating with flux foam 1, dip into a soldering tank 2. Thereafter,
do not dip to clean. There is no danger of flux penetration in pro-
cesses 1 and 2, but penetration will occur with dip cleaning, causing
contact and rotational defects. Clean the flux as shown in Figure 1,
tilting the Switch 45° or more and using a brush to apply the solvent
only to the back of the board. It may also be cleaned by dipping only
the back of the board into solvent and then using a brush to clean.
Dip Soldering
Dip into flux solvent 1, and then into a soldering tank 2. The dipping
time in process 1 is a maximum of 2 seconds. As shown in Figure 2,
avoid flooding the top surface of the printed circuit board with flux.
Using a brush to apply flux further reduces the danger of flux pe-
netration. As shown in Figure 2, a brush should be used while tilting
the board 45° or more. Flush flux as described above under Auto-
matic Soldering.
Using a Soldering Iron
Use a 30-W soldering iron at a temperature of 350°C for a maximum
of 3 seconds, and flush as described above.

5. Confirm that the (–) push-button can no longer be pushed
after reaching the lower limit of (“0”). This completes the
setting.
