Ultra Subminiature Basic Switch

Precautions

Refer to General Information.

Use the Switch within the rated voltage and current ranges, oth-

erwise the Switch may have a shortened durability, radiate heat,

or burn out. This particularly applies to the instantaneous volt-

ages and currents when switching.

● Soldering

· General Precautions

Before soldering the Switch on a multilayer PCB, test to con-

firm 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 rectifica-

tion 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 fol-

lowing 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.
