The illustrations and drawings are for solder terminals models.
Refer to "Terminals/Appearances" of the previous page for details on models with Straight PCB terminals.
When ordering, replace @ with the code for the terminal that you need.
Precautions
★Please refer to "Basic Switches Common Switches" for correct use.
●Degree of Protection
• Do not use this product underwater.
Although molded lead wire models satisfy the test conditions
for the standard given below, this test is to check the ingress of
water into the switch enclosure after submerging the Switch in
water for a given time. Satisfying this test condition does not
mean that the Switch can be used underwater.
• JIS (Japanese Industrial Standards)
C0920 (Waterproof test of the electrical machinery/appliance
and wiring materials)
Degree of protection: 7, Model: Waterproof
• IEC (International Electrotechnical Commission)
Publication 529 (Degrees of Protection Provided by
Enclosures)
Degree of protection: IP67
• Do not operate the Switch when it is exposed to water spray,
or when water drops adhere to the Switch surface, or during
sudden temperature changes, otherwise water may intrude
into the interior of the Switch due to a suction effect.
• Prevent the Switch from coming into contact with oil and
chemicals.
Otherwise, damage to or deterioration of Switch materials may
result.
• Do not use the Switch in areas where it is exposed to silicon
adhesives, oil, or grease. Otherwise faulty contact may result
due to the generation of silicon oxide.
●Soldering
• When soldering the lead wire to the terminal, first insert the
lead wire conductor through the terminal hole and then
conduct soldering. Complete soldering within 3 seconds using
a soldering iron with a capacity of 50 W max and a tip
temperature of 300°C max. Also, do not apply external force to
the Switch for 1 minute after soldering.
Improper soldering involving an excessively high temperature
or excessive soldering time may deteriorate the characteristics
of the Switch.
When performing automatic soldering, solder at 260 °C max
and complete soldering with 5 seconds. Pay careful attention
so that flux or solder liquid does not flow over the edge of the
PCB panel.
●Side-actuated (Cam/Dog) Operation
• When using a cam or dog to operate the Switch, factors such
as the operating speed, operating frequency, push-button
indentation, and material and shape of the cam or dog will
affect the durability of the Switch. Confirm performance
specifications under actual operation conditions before using
the Switch in applications.
