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

Honeywell Series TL Toggle Switch, 20A Current Rating, 28V DC Contact Dc Voltage - 2TL222-7E

This toggle switch is a manual bushing-mount control intended for switching dual circuits in industrial and electrical installations. It provides a three-position selector arrangement for flexible routing of signals or power and is designed for environments requiring sturdy connections and a non‑illuminated actuator.

Features and Benefits:

• Double-pole double-throw contactry supports simultaneous circuit switching
  Rated for 20 A contact current to handle high-load switching
  Accepts 125V AC and 28V DC for AC and DC system compatibility
  Screw-type terminals deliver secure, field-serviceable connections
  Operates across -65 °C to 71 °C for wide temperature deployments
  Non‑illuminated metal actuator reduces wiring complexity

Applications

• Suitable for control panels requiring circuit polarity selection
  Ideal for machinery requiring changeover of two power lines
  Used with automation relay banks for manual override functions
  Can be used for vehicle or mobile equipment low-voltage switching
  Used for test rigs that need robust, repeatable manual switching

What contact arrangement does it use and why is that useful?

It uses a double-pole double-throw arrangement which permits independent switching of two separate circuits, enabling changeover or isolation tasks without additional components.

How are electrical connections MADE and maintained?

Connections are secured via screw terminals, allowing straightforward installation, periodic retightening and simple replacement in the field.

What operating positions does the mechanism provide?

The mechanism offers three distinct switch positions in an on-on-on configuration to enable multiple routing states for each pole.

How does the temperature capability affect installation choices?

The operational range from -65 °C to 71 °C allows use in both low-temperature storage environments and moderately elevated industrial ambient conditions without derating.
