Leviton DT160-1LW Countdown Timer Switch

The Leviton DT160-1LW provides four preset times (10-20-30-60 minutes) for fan and light control. It is designed for single-pole installations and supports a broad load range, including LED/CFL and traditional incandescent motors. The Green Flex Sleeve helps wire to ground even when no neutral is present, though a ground wire remains required. This makes it a solid choice for older walls with no neutral in the box and for installations where a quick, reliable auto-off is desired. Best for: bathrooms and small utility spaces where a quick, configurable timer is needed.
Why selected: Strong preset options, straightforward wiring, and compatibility with common fan/motor loads. The no-neutral variant suits many existing homes. Caution: If your wallbox lacks a ground, you’ll need to address grounding before installation.

Buying Guide: How To Choose The Right Timer Switch
- Load compatibility: Check if the timer supports LED/CFL, incandescent, and motor loads you plan to control. Look for a rating like 600W LED/CFL, 1800W incandescent, or ½ HP for fans.
- Neutral vs. no-neutral: If your wall box lacks a neutral wire, choose a model designed for no-neutral installation or be prepared to rewire or use the green sleeve option as needed.
- Presets and control style: Decide if you prefer fixed presets (5–60 minutes), a dial-based mechanic, or a touch button interface for quick setup and overrides.
- Grounding and safety: A ground connection is typically required. Verify box grounding and follow local electrical codes during installation.
- Placement and use case: For bathrooms, laundry rooms, and closets, aim for timers with simple multi-minute options to automate lights and exhaust fans without overprocessing.
