TWTD Series — Full Size NEMA Pushbuttons
TWTD Series: Heavy duty switches built to last
Key features:
• Variety of button sizes up to 2 9/16” (65mm)
• Rugged construction includes chrome plated zinc locking ring die cast zinc
mounting threads, screw mounted contact blocks
• LED or incandescent illumination
• Transformer or full voltage
• Transparent contact windows
• Slow make, double break self-cleaning contacts
• Modular construction for maximum exibility
• Double nickel plated terminal screws
• Available assembled or as sub-components
• Type 4x and IP65 watertight/oiltight panel
• Large M3.5 screw terminals with captive sems plate
The rugged series of TWTD switches offers both variety and durability in an
attractive design.
With button sizes up to 2 9/16” (65mm), chrome plated zinc locking rings, die
cast zinc mounting threads, steel anti-rotation rings, and self cleaning contacts,
the TWTDs are here to stay.
The TWTD series also offers either LED or incandescent illumination in full volt-
age and transformer models.
Transparent contact windows allow the viewing of IDEC’s self cleaning slow-
make/slow-break contacts.
Regardless of your switching needs, the TWTD series provides the kind of long
lasting, industrial strength quality you’ve come to expect from IDEC.

1. The truth table indicates the operating position of
contact block when the operator is switched to that
position.
X = On (closed contacts) O = Off (open contacts)
X X = Overlapping Contacts: Remain on (closed
contacts) when switch is moved between these two
positions.
2. All knob and lever selector switches come in black.
Other colors are available by ordering the knob or lever
separately.
3. Custom contact arrangements available, see page 739.

2. N/D = No circuit number designation required in assembled part number.
3. X = On (closed contacts) O = Off (open contacts). X X Overlapping contacts remain on (closed) when switch is moved between these two positions.

Operating Instructions
Adjustment for Panel Thickness
Each unit is shipped with several waterproof gaskets which are 0.06” (1.5mm)
and 0.12” (3mm) thick. Combine the gaskets for a dimension approximately equal
to panel thickness and install between the bezel and the body of the unit.
A trim washer must be used with a thrust washer or a nameplate to prevent the
control unit from rotating in the mounting hole. When using anti-rotation rings
(trim washer with thrust washer or nameplate), install as shown below.
Selector Switches
The operator shaft of each unit has a recess to identify in which direction to
install the handle. Align the handle with the recess. Press color insert (TW-HC1)
into the Standard Operating Positions.

Installation of LED Illuminated Units
Transformer units are recommended for use in areas subjected to inductive
noise. When using full voltage types, install a protection diode as shown below.
Use diode with DC power supply to protect against surges and noise.
Make sure that LED illuminated units are installed with correct polarity, as indicated at
the terminals.
Application Example For Push-To-Test Pilot Light
A typical application of illuminated pushbuttons is a push-to-test pilot light
which can be used to check the lamp/LED circuit.
