D2LS
Ultra Subminiature Basic Switch
Precautions
Refer to General Information.
Cautions
Use the Switch within the rated voltage and current ranges, otherwise the Switch may have a shortened durability, radiate heat,
or burn out. This particularly applies to the instantaneous voltages and currents when switching.
· Manual Soldering
Soldering temperature: 350°C max. at the tip of the soldering
iron
Soldering time: 3 s max.
● Washing
The Switch is not sealed, and cannot be washed. Doing so will
cause the washing agent, together with flux or dust particles
on the PCB, to enter the Switch, resulting in malfunction.
Correct Use
● Soldering
· General Precautions
Before soldering the Switch on a multilayer PCB, test to confirm that soldering can be performed properly. Otherwise the
Switch may be deformed by the soldering heat on the pattern
or lands of the multilayer PCB.
Do not solder the Switch more than twice, including rectification soldering. An interval of five minutes is required between
the first and the second soldering.
● 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.
· Reflow Soldering (Surface Mounting)
Solder the terminals within the heating curve shown in the following diagram.
The peak temperature may vary depending on the reflow bath
used. Confirm the conditions beforehand.
