Safety Precautions
Instructions
•Turn off power to the L6 series control units before installa-
tion, removal, wiring, maintenance, and inspection. Failure
to turn power off may cause electrical shocks or fire haz-
ard.
•To avoid b urning your hand, use the lamp holder tool when
replacing lamps.
•F or wiring, use wires of proper size to meet the voltage and
current requirements. Improper soldering may cause over-
heating and create a fire hazard.
Replacement of Lens and Marking Plate
•Removal
Remove the operator (color lens, marking plate, lens holder, and
spring) by holding the color lens recesses with the Lens Removal
Tool (MT-101) and pulling it out. Remove the marking plate by
disengaging the latches between the color lens and lens holder.
The marking plate must be engraved on the front side as shown
below.
When using a color film, insert it between the color lens and
marking plate.
Illumination selector knob can be removed by turning the knob and
pulling it out.
•Installation
Place the marking plate on the lens holder in the correct direction,
and press the color lens onto the lens holder to engage the latches.
Insert the lens holder into the housing in the correct direction.
Marking
For L6 series illuminated pushb uttons, legends and symbols can be
engraved on the built-in marking plates, or printed film can be
inserted under the lens.
•Marking Plate & Engraving Area
Replacing the LED Lamp
Lamps can be replaced using the lamp holder tool (OR-44) from the
front of the panel, or by removing the contact block from the
operator unit.
•Removing the LED lamp from the front of the panel
1. Slip the lamp holder tool onto the lamp head. Then push slightly,
and turn the lamp holder tool counterclockwise.
2. Press the lamp head to remove from the lamp holder.
•Installing the LED lamp from the front of the panel
1. Insert the LED lamp head into the lamp holder. Make sure that
the lamp is pushed in completely.
2. Hold the bulb with the lamp holder tool (OR-44) as shown below.
3. Place the insertion guide of the lamp holder and the TOP mark-
ing side or the groove in the operator unit in the same direction.
Insert the lamp holder into the housing with the lamp holder tool.
Then push the lamp lightly and turn it clockwise to install.
•Replacing the LED lamp by removing the contact
block
The LED lamp can be replaced easily by removing the contact
block.
Panel Mounting
Remov e the contact bloc k from the operator . Insert the operator into
the panel cut-out from the front, then install the contact block to the
operator.
•Removing the contact block
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.
•Installing the contact block
Insert the contact bloc k with the T OP 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.
•Notes for mounting
Use the optional Ring Wrench (MT-001) to mount the operator onto
a panel. Tightening torque should not exceed 0.88 N·m. Do not use
pliers. Do not tighten with excessive force, otherwise the locking
ring will be damaged.

Instructions
Single Board Mounting
Wiring
Solder the terminal at 350°C within 3 seconds using a 60W solder-
ing iron. Sn-Ag-Cu type is recommended when using lead-free sol-
der. When soldering, do not touch the switch housing 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.
Use a non-corrosive rosin flux.
Notes on Terminal Cover
Insert the terminal cover into the contact block with the TOP mark-
ings on the contact block and the terminal cover in the same direc-
tion.
Note: When wiring, insert the lead wires into the terminal cover
holes before soldering.
L-Shaped Lever Contact Type
L-shaped lever contact types are avail-
able for 18-mm mounting centers,
except buzzers. (Rectangular types
have 24-mm mounting centers.)
To order L-shaped lever contact types,
specify “T” in place of “C” in the Type
No.

L-shaped Lever Contact
Mounting PC board terminal control units on a PC board offers the
following features.
Features
•Reduced installation labor, easy wiring, space saving, and stan-
dardization.
•Since the contact blocks on the PC board can be removed easily
using a locking lever, the L6 series control units are easy to main-
tain.
•Because the L6 series control units require no studs for f astening
the control unit to a PC board, special preparation of the control
panel is not needed.
Notes for Designing PC board and Circuit
•Use 1.6-mm-thick glass epoxy PC board with drilled holes.
•Design a circuit so that the L6 series control unit 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 carefully to prevent short circuit.

Note 1: When designing, note the alignment of centerlines of the contact
blocks and centerlines of the operators.
Note 2: The diameter of the terminal hole is 1.2 mm.

Installation and Removal of Contact
Blocks
Turn the locking lever to install and remove contact blocks on the
PC board using a screwdriver from a hole (standard contact ø6
mm, L-shaped lev er contact ø5 mm to ø6 mm) in the PC board. The
locking lever can be used for both standard contact types and L-
shaped lever contact types but determine location of the control
units so that the locking lever can be operated.
Hole diameter may vary to meet installation requirements. When
the locking lever can be accessed by using a screwdriver from the
upper or right space, holes are not necessary.
Mounting Holes and Assembly Procedure
Drill mounting holes in the panel as shown below. When the units
are mounted collectively, provide adequate clearance.
•Assembly Procedure
1. Install the operator to the panel.
2. Mount the contact block to the operator from the rear.
3. Turn the locking lever to lock the contact block.
4. Insert the PC board to terminals and solder.
Note 1: Make sure that each terminal is inserted into the PC board correctly.
Note 2: Do not apply tensile force to the connector cable for an extended
period of time.
Note 3: Do not expose the contact block to water.
Note 4: Ensure to lock contact blocks when the contact blocks are installed
on the operators.
Switch Guard for Single Board Mounting
Note: The panel depth is the same for control units with or without switch
guards. Both types can be installed on the same PC board.
