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.
