1. Switch mounting
Mount the switch to a smooth surface
using M4 screws. Tighten the screws with
0.3 to 0.5 N·m {3 to 5 kg·cm} torque. To
prevent loosening of the mounting
screws, it is recommended that spring
washers be used in combination with
adhesive material for locking the screws.
2. Adjustment of the operating device:
With respect to the position of the
operating device and the switch body, set
the position as indicated in the condition
on the right. 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.

Snap-in mounting type
3. Confirming insulating distance:
Before mounting and wiring, the
insulating distance between terminals
and between terminals and ground
should be checked for assurance of
proper distance. With respect to the
terminal connections, it is recommended
that receptacles with insulating sleeves
be used.
Also, consideration should be given to the
wiring not to apply force to the terminal
section normally.
4. Avoid using AV1 switches in the
following conditions:
• Locations where hydrogen sulfide gas
or other corrosive gases exist.
• Locations where gasoline, thinner, or
other inflammable or explosive gases
exist.
• Locations where there is dust and
refuse.
• For operation where the perpendicular
operating speed is less than 10mm/sec.
• For operation frequency of make/break
exceeding 60 cpm.
• For ambient temperatures exceeding
the range of –25°C to +85°C.
• For ambient humidity exceeding 85%
R.H.
• For use in a silicon atmosphere.
5. For use of AV14653F (1a1b type):
For the type AV14653F, the air distance
between the N.O. and N.C. contacts is
less than the required value of VDE. The
N.O. and the N.C. contacts can carry only
the same electric potential.
