Honeywell Series TL Toggle Switch, 20A Switch Contact Current, 277V AC Contact AC Voltage - 1TL1-4


This toggle switch provides a Compact electromechanical means to control circuits in industrial and electronic equipment. Designed for panel mounting, it offers single-pole, double-throw switching suitable for manual control tasks in automation and electrical assemblies. The device supports both maintained and momentary actuation modes and is intended for installations requiring a robust contact rating and recognised safety approvals.

Features and Benefits:


• SPDT contact arrangement enabling versatile circuit selection
• 20A contact current for high-load switching capability
• 277V AC rated for mains-voltage control applications
• Screw terminals for secure conductor connections
• Operates reliably from -65°C to 71°C for wide-range environments
• 17mm actuator length for accessible manual operation

Applications


• Suitable for control panels in factory automation systems
• Ideal for switching mains-fed lighting or signalling circuits
• Used with motor starters and control relays in machinery
• Can be used for manual override functions on electrical racks
• Suitable for retrofit into existing instrument panels needing Compact switches

What mounting preparation is required for installation?


A circular panel aperture of 12.4mm is required to accept the bushing mount and secure the switch in place.

How is the device terminated electrically?


Conductors are fastened using screw-type terminals, allowing reliable clamp connections and straightforward replacement in the field.

What approvals support use in regulated installations?


The product carries CE, UL and CSA approvals to align with common industrial conformity standards.

How does the switch accommodate different user actions?


It provides two operation modes—maintained for steady states and momentary for transient actuation—so it can be configured for latching or push-to-operate control.
