The LB series is the shortest in the
industry, only 27.9mm deep behind
the panel. Reduces the size of
machines and control panels.
Short body
Removable contacts enable easy
wiring. Single board mounting
reduces installation time and
prevents incorrect wiring.

and removable at positions.
2. Two keys are supplied.
3. For Standard Bezel part numbers specify bezel shape in place of . 1 (round), 2 (square), 3 (rectangular)
4. For Flush Bezel part numbers specify:
-bezel shape in place of . 6 (round), 7 (square), 8 (rectangular)
- bezel material in place of . M (metallic), Blank (black)
5. See page 22 for contact operation.
6. See page 31 for dimensions.
7. For additional security, wave keys also available.
Add the letter “S” before the “T” in the part no. Example: LB1K-31ST1A
Besides the standard wave key (key number 0H), six other keys are available.
To order other keys, specify the key number as shown below:
Example: LB1K-31ST2B-1H (Key number is indicated on the key cylinder. Standard keys do not have a key number indication.)
8. If ordering standard wave key (0H), subcomponents are available, see next page.
9. If ordering other than standard wave key (for example, key number 6H), only completed switches are available.

Notes for Designing PC Board and Circuit
1. Use 1.6mm-thick glass epoxy PC board with drilled holes.
2. Design a circuit so that the LB series can operate within the rated voltage and current range. Make sure that inrush current and voltage do not exceed the rating.
3. Minimum applicable load is 5V AC/DC, 1mA on gold contacts.
4. Since the *2.8mm-wide terminal touches the PC board as shown below , short circuit may occur with pattern lines. Design a circuit that prevents short circuits.
1. When designing, note the alignment of the center lines of the contact blocks and operators.
2. The diameter of the terminal hole is ø1.2.
3. Hole diameter may vary to meet installation requirements. Determine the location and the size of the hole so that the locking lever can be operated.

Precautions & Instructions
• Turn off the power to the LB series control units before installation, removal,
wiring, maintenance, and inspection. Failure to turn power off may cause
electrical shocks or fire hazard.
• To avoid burning your hand, use the lamp holder tool when replacing the
lamps.
• For wiring, use wires of a proper size to meet voltage and current
requirements. Solder correctly according to the instructions in "Wiring" and
"Notes on Terminal Cover." Improper soldering may cause overheating and
create a fire hazard. Also, when using tab terminals, use receptacles of
appropriate size.
Wiring
1. Solder the terminals at 350°C within 3 seconds using a 60W soldering
iron. Sn-Ag-Cu type is recommended. When soldering, do not touch the LB
series with the soldering iron. Also ensure that no tensile force is applied
to the terminals. 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, terminal covers cannot be installed.
Standard Bezel
Flush Bezel
Operating Environment
• Do not use the LB series where corrosive gases exist or under an
environment exceeding the operating temperature and humidity ranges.
Otherwise, damage such as contact failure or change of the surface color
may occur.
• Major parts of the switch are plastic. Scratches or damage may occur
when scraped with a sharp object or if excessive load or shock is applied.
Note that this may cause operation and appearance failure of the operator
and bezel.
• Application of detergent, cutting oil, or special chemicals to the switch
may result in operation and/or appearance failure such as a change in
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.
Removing and Installing the Contact Block
1. Turn the locking lever on the contact block in the direction opposite to the
arrow on the housing. Then the contact block can be removed.
2. Insert the contact block with the TOP markings on the contact block and
the operator placed in the same direction. Then lock the units, turning the
locking lever in the direction of the arrow.

Replacing the Lens
Standard Bezel
From the opposite side of the TOP marking, remove the operator (lens,
marking plate, and lens holder) using the optional lens removal tool (MT-101)
by gripping the recesses of the color lens. Removing from the TOP side may
damage the metallic bezel.
Removing the Operator (standard bezel)
Flush Bezel
From the opposite side of the TOP marking, push the tip of a flat screwdriver
to the groove of the color lens and pull out the operator (lens, marking plate,
lens holder). Removing from the TOP side may damage the metallic
bezel.
Removing the Operator (flush bezel)
Replacing the Marking Plate
1. Remove the marking plate by pushing the lens from the back to disengage
the latches between the lens and holder, using the screwdriver as shown
below.
Note: A transparent film inside the lens holder is attached to the unit to make
it waterproof and cannot be removed.
2. Insert a marking plate into the color lens, and press the lens onto the
lens holder to engage the latches. Pay attention to the orientation of the
marking plate.

Notes on replacing the LED Unit
• When replacing the LED unit, make sure that static electricity is not
applied.
• Make sure that the LB series has cooled down before replacing the LED
unit.
• To avoid getting burned, be careful not to touch the unit while it is still hot.
Notes on Using Quick Connect Terminals
1. Use #110 tab quick connects, 0.5mm-thick.
2. When connecting the terminals on the left and center, make sure that
surfaces of the quick connects face each other. Otherwise, a short-circuit
may occur.

Correct Incorrect
3. Apply only horizontal force against the panel to the tab. The switch may
be damaged if a force other than a horizontal force is applied.
Installing Rubber Boots
When using the switches in enviroments subject to splashing water or an
excessive amount of dust, make sure to use an optional rubber boot. As
shown in the drawing on the right, remove the gasket from the operator,
and attach the rubber boot from the front (button side).
Standard Bezels
For rectangular and square units, pull the seals out of the rubber boot and place
them around the operator sleeve as shown below. Make sure that the seals are
not twisted or tucked inside and that the gasket is removed, otherwise waterproof
and dustproof characteristics are not ensured.

Instructions
Maintained Pushbuttons
Do not replace the buttons when the pushbutton is in the maintained position
as it may damage the internal mechanism. Also, do not remove the contact
block with the button in the maintained position. The contact may not
operate properly when the contact block is remounted.
Pushbuttons and Illuminated Pushbuttons with Switch
Guard
Do not apply force to the switch guard when the switch guard is not attached
to a panel. When opening the switch guard, do not open more than 180°. The
hinge may break.
Selector Switches
When turning the operator or key, make sure that they are turned to the
correct position.
Selector Switches with Key
Observe the following instructions to prevent malfunction or damage.
• Do not remove the key from any key retained position.
• In addition to the standard key (key number 0H), six other key numbers
are available. Use a key matching the number of the key cylinder. The
standard key does not have a key number indication.
• Keys are available in two types.
Key numbers 0H (standard), 1H, and 2H are reversible keys which can be
inserted in two ways.
Key numbers 3H, 4H, 5H, and 6H are non-reversible keys. Make sure of
correct insertion direction.
