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
Perform reflow soldering within the ranges shown in the terminal tem-
perature profile in the following diagram.
Washing
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.
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.
Reference: The following standards are used to determine compli-
ance for the six substances.
Lead:1,000 ppm max.
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.

Packaging Specifications
The specifications for B3U Switches packaged on embossed tape
are as follows:
B3U-1000 Series
B3U-3000 Series
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)
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.
Do not operate the plunger from the side. Doing so may deform or
damage the Switch.
