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

Honeywell Series TL Toggle Switch, 20A Switch Contact Current, 125V AC Contact Ac Voltage - 4TL1-1D

This toggle switch is a manually operated electrical control intended for use in industrial and instrumentation panels where a three-position selector is required. It provides a straightforward on‑off‑on switching function with multiple isolated circuits, suitable for control and signal routing tasks in automation and electrical assemblies. The unit is non‑illuminated and designed for bushing mounting with screw‑style terminations for secure connections.

Features and Benefits:

• 4PDT contact arrangement enabling simultaneous multi‑circuit control
  20A contact rating supporting high‑current switching needs
  Operates at up to 125V AC for mains‑compatible applications
  Rated for 28V DC for low‑voltage control circuits
  Terminal screws provide robust, serviceable wiring connections
  Wide temperature capability from -65°C to 71°C for harsh environments

Applications

• Suitable for controlling multiple relay coils in automation racks
  Ideal for switching between redundant power sources in control panels
  Used for routing signals in test and measurement benches
  Can be used for manual mode selection on industrial machinery

How is the switch mounted to a panel?

It fits through a panel aperture and secures via a bushing mount for a Compact fixed installation.

What actuator travel is provided for manual operation?

The exposed actuator length measures 26.67 mm, offering clear tactile engagement for deliberate switching.

Which Terminal type should I prepare for wiring?

The device uses screw terminals, so stranded or solid conductors crimped or sleeved provide reliable terminations.

What approvals cover its safety and conformity?

The component carries UL, CSA and CE approvals indicating compliance with the relevant safety and conformity standards.
