Industrial Toggle Switch
The Bryant 4821 is a brown single-pole double-throw toggle switch rated at 15 amps and 120/277 volts AC. It provides momentary contact action suitable for industrial control circuits and motor loads up to 2 horsepower. The device mounts in a standard wall box and uses screw terminals for secure back or side wiring connections.
Quiet Operation and Standards
The switch features a quiet mechanism that reduces audible clicking during actuation. It complies with NEMA WD-1 and UL20 standards for safety and performance in industrial environments. These certifications confirm the component meets established requirements for electrical starters and contactors used in machinery applications.
Straightforward Screw-Terminal Wiring
Installation involves connecting wires to the screw terminals using back or side entry methods. The 1.7 inch overall height fits standard wall boxes without modification. Ensure the circuit voltage matches the 120/277V AC rating and the load does not exceed 15 amps or 2 horsepower to avoid overheating or premature failure.

Questions about this item
How often will the screw terminals on the Bryant 4821 need retightening?
The screw terminals are designed for permanent installation and do not require periodic retightening under normal industrial use.
What is the first limit reached when the 15 A rating is held continuously?
The 15 A current rating is the limiting factor; sustained loads must not exceed 15 A at 120/277 V AC.
Does the toggle switch generate audible noise or heat during all-day operation?
The quiet-switch feature minimises audible click, and normal operation at rated load produces only minimal heat.
