Precautions
Be sure to read the precautions and information common to all Snap Action and Detection Switches, contained in the Technical User’s Guide,
“Snap Action Switches, Technical Information” for correct use.
■ Correct Use
■ Caution
Mounting
Electrical Ratings
The cover has the same electrical potential as the COM terminal. Do not
short-circuit the cover with a NO or NC terminal when mounting the
cover.
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.
Terminal Connection
cover
Do not use flow soldering or hand soldering to solder terminals.
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.
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.
R1 min
Operating body
• Set the Switch stroke to 70% to 100% of the overtravel (the difference between the operating position and the total travel position).
Preheating time:
60 to 120 s
• 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.
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.
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
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.
■ RoHS Directive Compliance
Insulation and Wiring
Models that are indicated as being RoHS compliant are free of the
following six substances.
Be sure that the installation conditions provide a sufficient insulation
distance between Switch terminals and other metal parts, lands, etc.
Lead:
1,000 ppm max.
Mercury:
1,000 ppm max.
Cadmium:
100 ppm max.
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.

correlate it to actual application requirements. Actual performance is subject to
Seller's Warranty and Limitations of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Seller representative at any time to
confirm actual specifications of purchased Product.
5. Errors and Omissions. The information in this publication has been carefully
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors, or omissions.
