■Precautions

Note: Be sure to read the precautions common to all Tactile Switches for correct use.

■Precautions for Correct Use

soldering

Do not exceed the following terminal temperature profile during

soldering in a reflow oven.

Washing

The 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.

Packaging Specifications

The packaging specifications for B3AL Switches in embossed

taping are given below.

Operation

• Do not repeatedly operate the Switch with excessive force.

Applying excessive pressure or applying additional force after

the plunger has stopped may deform the disk spring of the

Switch, resulting in malfunction.

• Be sure to set up the Switch so that the plunger will operate in a

straight vertical line.

If the plunger is pressed of-center or from an angle it may cause

deformation or damage to some parts.

• We recommend using a round bar with a diameter of at least 3

mm as the actuator.

Dust Countermeasures

Do not mount or use the Switch in areas that are subject to dust.

If dust is unavoidable, protect the Switch with a sheet or other

countermeasure.

Water and Drip Resistance

The switch is not water or drip resistant.

Do not use it in locations subject to water.
