Handling
Models with PCB Terminals
Do not use excessive force in handling the Switches. In particular,
take care to avoid dropping them because the terminals might bend
or break.

Screw-mounting Models
Tighten mounting screws to a torque between 0.2 to 0.24 N·m, using
M2.6 screws. Use plain washers or spring washers together with the
screws.

• Return the button to its original position
• The terminal insertion holes on the PCB must be at least 1 mm in

diameter.
Do not use dip cleaning. Doing so may result in flux penetration of
the Switch interior, causing contact and rotational defects. Clean
the flux as shown in Figure 1, tilting the Switch 80° or less 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 the
solvent and then using a brush to clean.
When applying flux solvent, the dipping time 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 penetration. When cleaning flux with a
brush, tilt the Switch 80° or less, as shown in Figure 1, in order to
prevent flux from flowing onto the switch mounting surface. Clean
flux as described above under Automatic Soldering.
Use a 30-W soldering iron at a temperature of 350°C for a
maximum of 3 seconds, and flush as described above.
Do not apply force to the terminals during soldering and for 3
minutes after soldering is completed. Doing so may result in
conduction or operation failure.
