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.

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.

•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.


•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.

●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.
