Commercial-grade toggle switch
This Hubbell three-way switch handles 20A at 120/277V AC for lighting circuits in commercial and residential buildings. The white toggle suits standard wall plates and supports multi-location control from two switch positions. It is built to commercial specifications for repeated daily operation.
Sustained load behaviour
Rated for continuous 20A duty, the contacts maintain stable resistance during extended use without derating. The 1 HP motor rating confirms suitability for inductive loads such as exhaust fans or small pumps. Back and side wiring terminals both accept solid or stranded conductors for secure long-term connections.
Installation and common issues
Back and side wiring options give flexibility for box fill and conductor routing. Common errors include reversing traveller wires between the two three-way locations and failing to identify the common terminal correctly. The switch fits standard wall boxes; no special tools are required beyond a screwdriver.

Questions about this item
Does the CSB320W generate noticeable heat or noise when switching a 20 A load continuously?
The CSB320W is a passive mechanical toggle switch with no moving parts that produce heat or audible noise during normal 20 A operation.
What wiring method and circuit voltage must already be in place for the CSB320W to function?
The switch requires a 120 V or 277 V AC circuit and accepts either back-wire or side-wire connections using standard solid or stranded conductors.
Can the CSB320W be paired with an existing three-way switch of a different brand on the same circuit?
Yes, the CSB320W follows standard three-way wiring conventions, so it will operate correctly alongside another UL-listed three-way switch regardless of brand.
