Hubbell DS320W 3-Way Dimmer Switch

The Hubbell DS320W is a 20 A rocker-style wall switch rated for 120/277 V AC circuits. It supports 3-way switching so a single light can be controlled from two locations. The white finish fits standard residential and commercial decor. UL Listed construction confirms compliance with recognised safety standards.

Replaces standard single-pole or worn 3-way switches

Upgrading is worthwhile when a circuit requires 20 A capacity or dual-voltage compatibility up to 277 V. The maintained rocker action provides positive on/off feel without illumination or pilot-light distraction. Impact-resistant housing suits high-traffic areas where standard toggles may loosen over time.

Verify wiring and box dimensions before ordering

Confirm the existing box accepts back or side wiring with 14 AWG to 10 AWG conductors. Screw-terminal connections require adequate conductor length for secure termination. Mounting holes are spaced 3.3 in centre-to-centre, so check the box pattern matches. This switch lacks a nightlight or locking feature if those functions are needed.

Questions about this item

What box depth and screw spacing does the Hubbell DS320W need for mounting?

The switch mounts with a 3.3 in centre-to-centre hole spacing and fits a standard single-gang wall box.

How do I wire the DS320W and which step is commonly missed?

Connect 14 to 10 AWG wires to the screw terminals using back or side wiring; the step often missed is tightening each terminal screw firmly after insertion.

When should the DS320W be replaced?

Replace the switch if the rocker becomes loose, the screw terminals show corrosion, or the impact-resistant body cracks from physical damage.
