NOTES
1. Fastening of the switch body
1) Use flat filister head M2.3 screws to
mount switches with less than a 0.29 N·m
torque. Use of screws washers or
adhesive lock is recommended to prevent
loosening of the screws.
2) Check insulation distance between
ground and each terminal.
3) When the operation object is in the
free position, force should not be applied
directly to the actuator or pin plunger
from vertical direction to the switch.
4) In setting the movement after
operation, the over-travel should be set
more than 70% as a standard. Setting the
movement at less than 70% of O.T. may
cause troubles such as miscontact and
welding due to small contact force of the
switch.
5) For a lever type, the force from the
reverse and side to the operation
direction should not be applied.

2. Soldering operations
Manual soldering should be
accomplished within 3 seconds with max.
350°C iron.
Care should be taken not to apply force
to the terminals during soldering.
Terminal portions must not be moved in
min.1 minute after soldering.
Also no tensile strength of lead wires
should be applied to terminals.
3. Selection of the switch
When specifying the switch, allow ±20%
to the listed operating characteristics.
4. Environment
Avoid using the switches in the following
conditions;
• In corrosive gases, such as silicon gas
• In a dusty environment

5. Cautions regarding use
When switching low-level circuits (6V DC
5mA, 12V DC 2mA, 24V DC 1mA), AV,
AV3/AVT3, AVL3 Au clad contact type
switches are recommended. When used
to switch inductive loads (relays,
solenoids, buzzers, etc.), it is
recommended that a proper spark
quench circuit is inserted in the switch to
prevent contact faults caused by electric
arcs. Care should be taken that
occurrence in AC load possibly shorten
the expected life.
6. Quality check under actual loading
conditions
To assure reliability, check the switch
under actual loading conditions. Avoid
any situation that may adversely affect
switching performance.
