3. Reversed action types
When the actuator is operated, the switching mechanism returns to the free position. Extraordinary force by pushing the plunger too
much is not put on the switching mechanism, which means stability in life.

NOTES
1. Regarding fastening of switch body
1) In fastening the switch body, use M4
mounting screws to attach switches with
the torque 1.5 N·m or less.
3. Soldering operations
Soldering should be done in less than 5
seconds, with a 60 watt iron (tip
temperature = 350°C max.). Care should
be taken not to apply force to the terminal
during soldering.
2) After mounting and wiring, the
insulation distance between ground and
each terminal should be confirmed as
sufficient.
4. Avoid using switches in the
following conditions:
2. Adjustment of the operating device
The operating device should be
• In corrosive gases such as hydrogen
sulfide.
positioned so that it applies no stress to
the pushbutton or actuator when the
switch is in the open position. If this
condition is exceeded, the mechanical
and electrical performance will be
impaired. In addition, the force applied by
the operating device should be in a
perpendicular direction. Even if the
pushbutton is used in the full total travel
position, there will be no influence on the
life of the switch.
• In flammable or explosive gases such
as gasoline or thinner etc.
• In a dusty environment.
• In an ambient humidity over 85%.
• In conditions where the perpendicular
operating speed is less than 0.1 mm/sec.
or more than 1,000 mm/sec.
• In a silicon atmosphere.
5. Others
Caution should be taken not to drop
switches.
