Precautions
★
Please refer to "Common Precautions" for correct use.
Surface Mount Switch
Caution
●Electrical
Ratings
• Confirm the contact load in order to select an appropriate
switch rating.
• Do not apply an excessive electrical load to the contacts,
otherwise the contacts may weld, resulting in a short circuit or
burning.
• Do not use flow soldering or hand soldering to solder
terminals.
• Conduct reflow soldering within the range shown in the
terminal temperature profile below.
Some reflow soldering devices have extremely high peak
values. Do a test in advance to confirm proper soldering
conditions.
• Do not conduct reflow soldering more than twice. Also provide
a time interval of at least five minutes between the first and
second reflow soldering processes to allow the Switch to
return to room temperature.
Heating the Switch continuously (without an interval) may
cause the edges of the Switch to melt and degrade the
characteristics.
• When printing for a cream solder process, a 0.13 mm screen
thickness is recommended.
• Be sure to provide local ventilation.
MAX255°C
220°C
180°C

Correct Use
●Mounting
• The cover has the same electric potential as the COM
terminal. Do not short-circuit the cover with a NO or NC
terminal when mounting the cover.

• Be careful of the following points. Incorrect handling may lead
to insufficient actuator return, Switch damage, or reduced
durability.
- Set the operating body in line with the direction of the
actuator movement, and make sure that the operating
body is completely separate from the actuator when the
Switch is in the free position (FP). When the actuator is
operated from the crosswise direction of the Switch, make
sure that the corner of the operating body has a minimum
radius of R1.
R1 min.

Preheating time
90 to 120 s
Heating time
40 s max.
●Printed
Circuit Boards
Special attention must be paid to the handling of printed circuit
boards after a Switch has been mounted onto them. Airborne
PCB particles may penetrate the interior of the Switch when
printed circuit boards are separated by cutting. Also, do not stack
printed circuit boards that have Switches mounted on them.
●Product
Specification Details
- Set the Switch stroke to 70% to 100% of the overtravel
(the difference between the operating position and the
total travel position).
- Do not subject the Switch to operations that involve strong
impact.
- Do not use the Switch as a stopper.
- Do not apply excessive loads to the cover or operate the
actuator from a direction other than a specified operating
direction.
- Do not use an adhesive to secure the Switch.
• A lubricant is used in the Switch. Some of the lubricant may
seep out because the Switch does not have an airtight
construction. Consider this possibility with respect to the
usage conditions when designing or using the Switch.
• This document provides only a partial list of specifications. It is
recommended that you request complete drawings and
specifications prior to purchasing or using the product.
●Application
Environment
Do not use the Switch in locations that are subject to toxic gas,
silicon, excessive dust, excessive dirt, high temperatures, high
humidity, sudden temperature changes, water splashes, or oil
splashes.
Otherwise, damage resulting by faulty contact of the Switch
contacts, corrosion, or other causes, or other functional faults
may occur.
●Insulation
and Wiring
Be sure that the installation conditions provide a sufficient
insulation distance between Switch terminals and other metal
parts, lands, etc.
●Cleaning
The Switch does not have an airtight construction, and it must
not be cleaned with cleaning fluids. Malfunctions may occur if the
cleaning fluid penetrates the interior of the Switch together with
flux or foreign matter from the surface of the PCB.
●Confirmation
with Actual Equipment
Be sure to confirm the quality of the product under the load and
environmental conditions that will be used during actual
applications.
