TWTD Series — Full Size NEMA Pushbuttons

TWTD Series: Heavy duty switches built to last

Key features include:

•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 fl exibility

•Double nickel plated terminal screws

•Available assembled or as sub-components

•NEMA 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 voltage 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.
