Leviton Countdown Timer Switch DT160-1LW
The Leviton DT160-1LW is a single-pole countdown timer switch designed for bathroom fans and household lights. It provides four preset times: 10, 20, 30, and 60 minutes. It supports up to 15A resistive loads and 1/2 HP/9.8A for fans or motors, with a shallow design that fits most standard wall boxes. A green flex sleeve wires to ground when no neutral is present; if a neutral is available, the sleeve can be removed and a neutral wired connection used. This makes it a solid option where neutrals are not in the box, but grounding remains essential. Best for: homeowners replacing a standard switch in boxes without a neutral conductor.
Why selected: Clear presets, straightforward installation, and compatibility with common bathroom loads. The timer’s compact form helps with space constraints in many retrofit projects. Caution: If the wall box has no ground, either install with a ground or consider a neutral-required model.
BN-LINK Countdown Digital Wall Timer Switch (6 presets)
This BN-LINK model offers six preset durations: 5, 10, 20, 30, 45, and 60 minutes, with a repeat function to automate the same countdown at the same time daily. It requires a neutral wire. A manual override button lets you cancel or override a timer when needed. It’s ideal for bathrooms, laundry rooms, and small offices where consistent shut-off scheduling saves energy. Best for: users who want repeatable daily timing and a simple one-touch experience.
Why selected: The repeat feature is helpful for routine dehumidification or periodic venting. Caution: If your box lacks a neutral, this model may not be suitable without wiring changes.
ENERLITES Countdown Timer Switch For Bathroom Fans and Lights (1–30 Min)
The ENERLITES unit provides a 1–30 minute countdown with a push-button interface and a neutral wire requirement. It is UL Listed and suitable for controlling bathroom exhaust fans, lights, and other small loads. Best for: users who want a compact, neutral-required timer with predictable short-duration shuts-offs. Limitation: Does not include longer presets beyond 30 minutes for some models, depending on stock and configuration.
Leviton DT130-1LW Countdown Timer Switch
The Leviton DT130-1LW offers a four-presets setup (5, 10, 15, 30 minutes) with no neutral required in some configurations, though installation can vary by wallbox. It supports typical bathroom fan and lighting loads and emphasizes a shallow form factor for easier fitment. Best for: users upgrading a standard single-pole switch who want quick, short-term control of a fan or light. Caution: Double-check neutral requirements for your box to ensure compatibility.
BN-LINK Countdown Timer For Bathroom Fans and Lights (6 presets)
This BN-LINK unit presents six preset durations: 1, 5, 10, 20, 30, and 60 minutes, with a touch-button interface and auto shut-off.

Caution: Ensure your wall box has a neutral conductor before purchasing.
Buying Guide
What should I consider before buying a bathroom countdown timer switch?
Neutral wiring: Some models require a neutral wire; verify your wall box wiring before selecting. No-neutral options exist but may demand a grounding setup.
Presets and range: Choose a timer with presets that fit your typical usage—short air exchange cycles or longer lighting sessions. If you need more than 60 minutes, look for models offering longer intervals or multiple packs.
Load compatibility: Check the timer’s electrical rating for fan motors, lights, and mixed loads. Ensure it supports the type and wattage of your devices.
Size and fit: A shallow or compact design helps fit into crowded wallboxes, especially in older homes. Consider whether a vertical or horizontal orientation better suits your box layout.
Durability and safety: For bathrooms, select UL-listed or UL-certified products for humidity exposure. Grounding and proper enclosure reduce shock risk in wet environments.
How to install timer switches safely?
Turn off power at the breaker before starting installation. Follow the manufacturer’s wiring diagram for neutral and ground connections. If uncertain, consult a licensed electrician, especially in homes with older wiring or complex circuits.
