Operation
• Do not repeatedly operate the Switch with excessive force.
• Be sure to set up the Switch so that the plunger will operate in a
Electrical Standards
Use the Switch within the rated voltage and current ranges, other-
wise the Switch may have a shortened life expectancy, radiate
heat, or burn out. This particularly applies to the instantaneous
voltages and currents when switching.
Soldering
Soldering Precautions
Reflow Soldering Conditions
Firmly attach a thermocouple to the surface of the terminals with
solder that has a high melting point and set the reflow oven so
that the peak temperature of the terminals is 260°C or less.
The following figure shows the temperature profile.
Manual Soldering
Applying excessive pressure or applying additional force after
the plunger has stopped may deform the disk spring of the
Switch, resulting in malfunction.

If the plunger is pressed of-center or from an angle it may cause
deformation or damage to some parts. This may result in deteri-
oration of durability or malfunction.

Washing
Standard Switches are 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.
PCBs
The Switch is designed for a 1.6-mm thick, single-side PCB.
Using PCBs with a different thickness or using double-sided,
through-hole PCBs may result in loose mounting, improper inser-
tion, or poor heat resistance in soldering. These effects will occur,
depending on the type of holes and patterns of the PCB. There-
fore, it is recommended that a verification test is conducted before
use.
RoHS Compliant
The "RoHS Compliant" designation indicates that the listed mod-
els do not contain the six hazardous substances covered by the
RoHS Directive.
Reference:
The following standards are used to determine compliance for the
six substances.
