FEATURES
• Ultra-low profile 1.4 mm .055 inch
(3.4 × 3.5 × 1.4 mm)
(.134 × .138 × .055 inch)
• The coil spring serves as the contact
and a high contact reliability is
achieved by the more than adequate
contact force and wiping effect. By
adopting gold-clad contact, a high
contact reliability is also achieved un-
der a small current, voltage and load.
• Horizontal and vertical mounting
types are available and detecting from
horizontal and vertical directions is
possible.
• High overtravel (1.3 mm .051 inch)
makes it easy for installation. (Long
stroke type)

NOTES
1. Mounting
1) The positioning of the switch should be
such that the pushbutton for the switch
should not directly apply force to the oper-
ating section in the free condition.
2) During both mounting and operation,
care must be taken to protect the pushbut-
ton from excessive stress, as this may
cause malfunctioning.
3) During mounting, the insulation dis-
tance between ground and each termi-
nals should be confirmed as sufficient.
2. Soldering
1) For manual soldering; Iron tip tempera-
ture max. is 320°C 608°F and soldering
should be completed within 3 seconds.
2) For reflow soldering; Perform soldering
reflow at a peak surface temperature of
the PC board not to exceed 245°C 473°F.
3) For cream soldering; Screen thickness
is recommended between 0.10 to 0.15
mm .004 to .006 inch.
4) During soldering, care should be taken
not to apply excessive stress to the termi-
nals as the resulting deformation may
cause malfunction.
5) Excessively high solder tab tempera-
ture and soldering iron wattage should
also be avoided as these factors may
harm switching performance.
6) As this switch is thin, using flux should
be avoided for the reason of the flux may
come inside of the switch and cause dam-
age.
3. Switch operations
1) The installation position of the activat-
ing unit that operates the switch should be
set at a distance of 1.4 to 1.9 mm .055 to
.075 inch from the center of the position-
ing projection for the type with boss (1.8 to
2.6 mm .071 to .102 inch for long stroke
type) and at a distance of 3.5 to 4.0 mm
.138 to .157 inch from the bottom for the
low profile type without (3.9 to 4.7 mm
.154 to .185 inch for long stroke type).
2) For 1 Form B contact type operation,
set the pushbutton so it returns to the free
position.
3) Avoid using the switch as a stopper
since it may cause trouble with the opera-
tions.
4) When using the switch to operate in the
sideways direction, ensure that the corner
roundness of the operating unit is more
than R1.
4. Environment
1) These switches do not have a sealed
construction. As such, the construction of
the equipment in which the switches are
to be installed should be given careful
consideration when the switches are to be
used in locations where corrosive gases,
silicon or other substances which will ad-
versely affect the contacts are used,
where there is a high concentration of
dust or where the switches may be ex-
posed to condensation or water. Using
switches in locations like these may cause
malfunctioning.
2) Avoid using this switch in high-temper-
ature, high-humidity or condensation-
forming environments and avoid allowing
droplets of water to remain on the switch
or come into contact with it. These condi-
tions may interfere with the performance
of the switch (resulting in short-circuiting,
etc.). Use the type with the gold contacts
in applications involving trains, aircraft,
motor vehicles or medical equipment
where the switch must satisfy safety and
high reliability requirements. Please con-
sult with us for the applications required
high reliability.
3) Because the humidity range differs de-
pending on the ambient temperature, the
humidity range indicated below should be
used. Continuous operation of the switch
is possible within this range, but continu-
ous use near the limit of the range should
be avoided.
• This humidity range does not guarantee
permanent performance.
5. Quality check under actual loading
conditions
1) Consult with us if this switch is to be
used outside its ratings.
2) To improve reliability, check the switch
under actual loading conditions.
6. Breakdown mode
For the switch breakdown mode, shorts,
open circuits, or rises in temperature
should be considered. For a device to be
safe so that it does not create any adverse
effect, ensure that a protection circuit or
protection device is in place to protect
against a possible switch failure. Also,
please make sure that sufficient redun-
dancy is built into the system in order to
ensure safety.
