Honeywell Technologies Toggle Switch, Bushing Mount, On-Off, 4PDT, Screw Terminal, 28 V dc, 125 V ac

Honeywell Series TL Toggle Switch, 20A Switch Contact Current, 4PDT Contact Configuration - 4TL1-2D

This toggle switch provides manual selection between electrical circuits for use in industrial and equipment panels. It is designed for panel mounting via a threaded bushing and offers a straightforward on-off actuation with a three-position arrangement that includes a central inactive position. The control suits environments where robust current switching and compatibility with common AC and DC systems are required.

Features and Benefits:

• 20A contact rating delivers high-current switching capacity
  4PDT contact arrangement allows simultaneous control of four circuits
  Screw terminals enable secure, serviceable wiring connections
  Compatible with 125V AC and 28V DC for mixed-voltage systems
  Operates from -65°C to 71°C for wide temperature tolerance
  Actuator length 26.67mm provides positive manual engagement

Applications

• Suitable for industrial control panels requiring multi-circuit switching
  Ideal for machinery where simultaneous circuit changeover is needed
  Used with control relays and contactors in automation systems
  Can be used for electrical test rigs needing a NEUTRAL centre position

How is the switch mounted to a panel?

It fits through a panel aperture and secures using the bushing for a robust, fixed installation.

What Terminal method is provided for electrical connections?

Wire connections are MADE via screw-type terminals that permit clamping of conductor ends and straightforward maintenance.

What switching configuration is available for circuit selection?

The mechanism provides an off-none-on arrangement across a four-pole double-throw layout to switch multiple independent circuits.

Which approvals cover suitability for regulated installations?

It carries recognised approvals from CE, UL and CSA indicating conformity with specified safety standards.
