•Use 1.6-mm-thick glass epoxy PC board with drilled holes.
• Design a circuit so that the LB/LBW series can operate within the rated voltage and current range. Make sure that inrush
current and voltage do not exceed the rating.
• Minimum applicable load is 5V AC/DC, 1 mA on gold contacts. Applicable range is subject to the operating condition and
load.
• Since the *2.8-mm-wide terminal touches the PC board as shown on the right, short circuit may occur with pattern lines.
Design a circuit that prevents short circuits.

5. Solder the terminals.
Before soldering, make sure that each terminal of the contact
block is securely inserted into the PC board holes.
LED Kit UP Unit
•Turn off power to the unit before installation, removal,
wiring, maintenance, and inspection.
Failure to turn off may cause electrical shocks or fire
hazard.
•For wiring, use wires of a proper size to meet the volt-
age and current requirements.
•Improper soldering or failure to tighten the terminal
screw may cause overheating and fire.
Polarity
Pay attention to the polarity of the power supply as UP series units
do not contain a diode for protection against reverse polarity. The
long terminal is positive and the short terminal is negative.
Current Limiting Resistor
When using a UP series unit without a built-in current limiting
resistor, connect an external current limiting resistor. Calculate the
resistance using the following formula.

See page 66.
Wiring
Solder the terminal at 350°C within 3 seconds using a 60W
soldering iron. SnAgCu type lead-free solder is recommended.
When soldering, do not touch the pilot light housing with the
terminal. Do not bend the terminal or apply excessive force to the
terminal.
Notes on Panel Mounting
Tightening torque should not exceed 0.49 N·m. Do not use pliers.
Do not tighten with excessive force, otherwise the locking ring will
be damaged.
PC Board and Circuit Design
Use glass epoxy copper clad laminate, double-sided through-hole
PC boards with a thickness of 1.6 mm.
Example of single board mounting
Note: Make sure
that the LED kit is
inserted into the
UP series unit.
Temporary mounting
1. Note the polarity of the
terminals and insert the
terminals to the PC board.
2. Make sure that part A of the
LED kit is pressed tightly
to the PC board. Bend the
terminals sideways as shown
on the left.

Safety Precautions
Instructions
Wiring
1) Solder the terminals at 350°C within 3 seconds using
a 60W soldering iron. Sn-Ag-Cu type is recommended
when using leadfree solder. When soldering, do not touch
the LB series with the soldering iron. Also ensure that no
tensile force is applied to the terminal. Do not
bend the terminal or apply excessive force to the
terminal.
2) Use non-corrosive liquid flux.
Terminal Cover
Solder/tab terminal
Insert the terminal cover into the contact block with the TOP
markings on the contact block and the terminal cover in the
same direction.
Note: When wiring, insert the lead wires into the terminal
cover holes before soldering.
After wiring, the terminal covers cannot be installed.
Standard Bezel
Flush Bezel
Operating Environment
• Do not use the LB/LBW series where corrosive gases ex-
ist or under an environment exceeding the operating tem-
perature and humidity ranges. Otherwise, damages due to
contact failure or change of surface color may occur.
• Major parts of the switch are plastic. Scratches or dam-
ages may occur when scraped with a sharp object or
applied with excessive load or shock. Note that this may
cause operation and appearance failure of the operator
and bezel.
• Adherence of detergent, cutting oil, or special chemicals to
the switch may result in operation failures and appearance
failures such as change of surface color.
Handling
Contacts (micro switch)
When using NC (normally closed) and NO (normally open)
contacts of the same microswitch, avoid connections of
different voltages, or connections of different types of power
supplies. Failure to observe this instruction may cause a
short-circuit.
Protection against oil (IP65)
The LB series has been tested according to JIS C 0920:
Appendix 1 by using water insoluble cutting oil Class N3,
No. 8 (JIS K 2241) to prove that the switches will not be
damaged by oil drops or splashes. This may not apply to
special types of oils. Contact IDEC for details.
