Precautions

Be sure to read the precautions common to all Tactile Switches, contained in the Technical User’s Guide, “Tactile Switches, Technical Information”

for correct use.

■ Precautions for Correct Use

Soldering

Packaging Specifications

Perform reflow soldering within the ranges shown in the terminal tem-

perature profile in the following diagram.

The specifications for B3U Switches packaged on embossed tape

are as follows:

Washing

Standards

Package

Conforms to JEITA.

B3U Switches 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.

3,500 Switches (B3U-1000 Series)

4,000 Switches (B3U-3000 Series)

Heat resistance 50°C for 24 hours (without deformation)

Compliance with RoHS Directive

The “RoHS Compliant” designation indicates that the product does

not contain the following six hazardous substances covered by the

RoHS Directive.

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 disc spring of the Switch, resulting in mal-

function. (Maximum force = 30N)

Reference: The following standards are used to determine compli-

ance for the six substances.

Lead:1,000 ppm max.

Be sure to set up the Switch so that the plunger will be pressed

straight in. The life of the Switch may be reduced if the plunger is

pressed off-center or from an angle. Do not apply pressure from

above or below the plunger. Doing so may deform or damage parts

or cause faulty operation.

Mercury:1,000 ppm max.

Cadmium:100 ppm max.

Hexavalent chromium:1,000 ppm max.

PBB:1,000 ppm max.

PBDE:1,000 ppm max.

Storage and Operating Environment

Do not store the product under the following conditions to prevent

discoloration and other deterioration of the terminals.

1. Locations subject to high temperatures or humidity

2. Locations containing corrosive gases

3. Locations subject to direct sunlight

The Switch is not provided with a watertight or drip-proof construc-

tion. Do not install or operate the product in locations subject to water

spray or splashes.

Do not operate the plunger from the side. Doing so may deform or

damage the Switch.
