Honeywell Technologies Toggle Switch, Bushing Mount, On-On, SPDT, Screw Terminal, 277 V ac

Honeywell Series NT Toggle Switch, 15A Switch Contact Current, IP68 - 1NT1-3

This toggle switch provides a manual two-position changeover mechanism intended for industrial control panels and equipment that require a simple on–on selection. It is designed for panel installation with a threaded bushing mounting style and utilises screw‑type terminations for secure wiring in electrical and automation assemblies.

Features and Benefits:

• SPDT contact arrangement enabling single‑pole changeover functionality
  Rated for 15 A current to handle higher load circuits
  Contact voltage capability up to 277V AC for mains applications
  Temperature range from −40 to 71 °C for varied environment operation
  IP68, IP67 ingress protection for exposure to water and dust
  Meets CSA, UL, CE approvals for regulated installations

Applications

• Suitable for control panels in factory automation systems
  Ideal for switching mains‑fed actuator circuits
  Used with distribution equipment requiring manual changeover
  Can be used for marine or outdoor enclosures needing ingress protection
  Suitable for maintenance panels where screw terminals simplify rewiring

What mounting hole size is required for installation?

The panel cut‑out dimension required for fitting the threaded bushing is 12.4 mm, allowing a secure panel mount.

How does the actuator profile affect accessibility?

The actuator extends 17 mm, providing a tactile lever length that aids operator access through small panel apertures.

Which Terminal arrangement is provided for electrical connections?

Screw terminals are provided to permit standard cable lugs or stranded conductors to be clamped reliably.

What mechanical footprint should be allowed behind the panel?

The switch has a body depth and overall width requiring approximately 33.5mm lateral clearance and 22mm from front to rear envelope for mounting considerations.
