Precautions
Note:
■
Soldering
Perform reflow soldering within the ranges shown in the terminal
temperature profile in the following diagram.
Washing
B3U Switches cannot be washed. Doing so will cause the wash-
ing 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 com-
pliance for the six substances.
Lead:
Mercury:
Cadmium:
Hexavalent chromium: 1,000 ppm max.
PBB:
PBDE:
Storage and Operating Environment
Do not store the product under the following conditions to prevent
discoloration and other deterioration of the terminals.
The Switch is not provided with a watertight or drip-proof con-
struction. Do not install or operate the product in locations subject
to water spray or splashes.
1. Locations subject to high temperatures or humidity
2. Locations containing corrosive gases
3. Locations subject to direct sunlight
Precautions for Correct Use
Refer to Safety Precautions in the Tactile Switches (Cat. No. X037) for details on general safety precautions.

Operation
Do not repeatedly operate the Switch with excessive force. Apply-
ing excessive pressure or applying additional force after the
plunger has stopped may deform the disc spring of the Switch,
resulting in malfunction.
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.
