Light-emitting diodes (LEDs) are P–N junction semiconductors with mechanisms called “junction electro-luminescence.” Application of
direct current results in radiation or emission of a monochromatic light.
Different semiconductor materials produce different wavelengths of light as shown below:
Advantages of Using LEDs
• LEDs are used when heat generated by incandescent lamps would damage nearby equipment or interfere with a preci-
sion process. This is particularly advantageous when multiple lights are grouped.
• LEDs can operate at low temperatures which would cause incandescent lamps to fail, since glass cracks during rapid
cooling.
• LEDs consume 50 times less power than incandescent lamps, thereby reducing energy consumption.
• LEDs last 500 times longer than incandescent lamps. LEDs average a million hours (114 years) while incandescent lamps
average 2000 hours.
• LEDs do not generally “blow out” unless subjected to a severe overvoltage. They exhibit a half-life type dimishment in
brightness over time. After 50,000 hours (6 years) of use, IDEC LEDs will retain approximately half of their original inten-
sity.
• IDEC’s SUPERBRIGHT LEDs have high visibility.
• LEDs require little or no maintenance because of long life and high reliability.
IDEC Recommendations
For optimum results, especially when using switches and pilot lights in operating environments which are conducive to overheating, use
IDEC LED illuminated units. Transformers are available for use with incandescent illuminated units, which operate at lower voltages to
avoid overheating.
When IDEC’s L-120L lamp is used, make sure ambient temperatures do not exceed 30˚C (86˚F). If a lamp
from another supplier is used, it should be rated for less than 1.8 watts (15mA at 120V AC), with ambient
temperatures as stated above.
Filament-type incandescent lamps operate within the following parameters.
Light output and life expectancy depend on operating voltage. Light output varies to the 3rd or 4th power of the voltage. Life expectancy
varies inversely to the 12th power of voltage. In other words, over-voltage of 5% reduces life expectancy by 50%. Under-voltage of 5% dou-
bles life expectancy at the price of light output efficiency.
Inrush current (initial current through the filament) has an adverse effect on life expectancy. Cold resistance (room temperature) will have a
more detrimental effect than hot resistance to inrush current. Life expectancy of incandescent lamps can be maximized by reducing occur-
rences of cold resistance to inrush current.
Continued intermittent flashing will significantly reduce life expectancy. When using an incandescent lamp with a tungsten filament, flash-
ing will not reduce life expectancy as long as light output does not exceed that of steady burning.
When an incandescent lamp must withstand shock and vibration, use low voltage/high amperage (5–6V/60–120mA) lamps. These lamps
have a short, thick filament with a high resonant frequency.
Provide cooling by using a heat sink, particularly when multiple incandescent lamps are grouped or when air circulation is limited. Make
sure ambient temperatures do not exceed 100˚C (212˚F) for maximum life of incandescent lamps.

1. IDEC offers assembled and sub-assembled switches and pilot lights for your convenience. In some cases there is a cost difference, with sub-assembled units
costing slightly less. Since assembled units are custom made to your order, a couple of days for assembly is added to delivery . To minimize delivery or inven-
tory requirements, it is recommended that switches and pilot lights be ordered as sub-components.
2. When ordering pilot lights or illuminated pushbuttons, make sure to specify the color code in place of the asterisk in the part number, (LED or incandescent lamp
included). Spare lamps can be ordered and are listed with sub-assembly components.
3. Accessories, such as locking ring wrench, lens removal tool, and lamp holder, are available to make installation and assembly easier. IDEC recommends using
these accessories and is not responsible for damage as a result of using the wrong tool.
4. Marking plates are available for switches and pilot lights which feature a flat lens. Printed mylar (not included) can also be inserted under lens for labeling pur-
poses.
5. Nameplates are available for TW, 7/8" (22mm), HW 7/8" (22mm),and TWTD series, Ø1–13/64" (30mm). For prompt delivery, order standard legends. Custom
engraving is also offered for an additional charge.
1. Use the appropriate lamp holder to remove or install LED or incandescent lamps. Using pliers will damage the lamp.
2. When mounting switches and pilot lights into a panel, use locking ring wrench.Using pliers or tightening excessively will damage the locking ring.
3. A series, 21/64" (8mm), can be mounted on a panel 0.019" (0.5mm) to 0.236" (6mm) thick.
4. LW 7/8” (22mm), TW, 7/8" (22mm), and TWTD series, Ø1–13/64" (30mm), feature an adjustment ring for mounting on a panel 0.038" (1mm) to 0.236" (6mm)
thick. Using a nameplate or an anti-rotation ring adds 0.031" (0.8mm) to the panel thickness.
5. When applicable, solder terminals within 20W/5sec or 260˚/3sec without exerting external force to the terminals. Use a non-corrosive resin liquid flux.
6. The operating voltage for LED units represents a complete DC value. When using a pulsing voltage, such a full-wave rectification, keeppeak currents within the
forward current If. Peak currents exceeding If may shorten the life of the LED lamp.
7. To avoid a short circuit, never connect NO and NC contacts to different voltages or power sources.
8. Optimum performance of TW and TWTD illuminated pushbuttons, selector switches, and pilot lights is obtained with IDEC LED and incandescent lamps.
9. For maximum life of incandescent lamps (approximately 2000 hours), use within the rated operating voltage. If it is necessary to use a higher voltage, keeping
ambient temperature below 30˚C (86˚F)will help prolong the life of an incandescent lamp.

General Instructions

Engraving
Area
Color Lens Marking Plate Lens Holder
Panel Mounting
Before any unit can be mounted into a panel, the contact block must be removed. Slide metal locking lever and pull contact off. Loosen and
remove the locking ring and square anti-rotation ring from the operator and insert operator through panel cutout from the front of the panel.
Slide on anti-rotation ring and tighten locking ring, using locking ring wrench (MT-001). Slide contact block onto operator, observing TOP
marking on both parts. Slide metal locking lever in direction indicated by LOCK. The yellow plastic safety lever lock can then be snapped onto
the locking lever; this will prevent vibration or maintenance actions from releasing the contact from the operator.
PCB Mounting
Being able to separate the contacts from the operator allows for assem-
bly of the front panel components (operator and lens) to be performed in
tandem with the PC board assembly and soldering. For applications
where multiple rows of pushbuttons are mounted closely together, or
where other components may obstruct access to the contact locking
lever, be sure to include access holes in the PC board (refer to PC board
layout dimensions for location). Also be sure to allow for space above
and to the side of contact to ensure that no components block the con-
tact block locking lever. PC board pins are designed to rest on the PCB,
take this into consideration to ensure that pins do not short closely
spaced traces.
Pushbutton Assembly
Lamp Installation
Lamps can be replaced in two ways:
1. If contacts are accessible (or pushbutton not installed in a panel) then
it is easiest to first remove the contacts from the operator. This will
allow easy access to the lamp/lamp-holder assembly. Grab lamp,
depress slightly, and turn counter clockwise. Lamp can then be
removed by pushing it back through the lamp holder.
2. If contacts are not accessible, then the lamp can be replaced by first
removing the lens from the operator. Just pull lens straight out either
with a fingernail or optional lens removal tool (MT-101). Lamp/lamp-
holder assembly can then be removed with lamp removal tool (OR-44).
Insert lamp removal tool through operator, depress slightly, turn counter
clockwise, then pull lamp/lamp-holder assembly out. Lamp can then be
removed by pushing it back through the lamp holder.
Engraving Lenses
All buttons and lenses can be engraved directly on the outside surface.
Illuminated lenses also allow for engraving on a plate that is underneath
the colored section of the lens. Remove the colored section of the lens
by pulling on the edge while simultaneously unhooking it from the
latches on the lens holder. The marking plate will then be accessible. It
can then be engraved or a thin marked insert (such as mylar or paper)
can be sandwiched between the marking plate and colored section of
the lens.
