Leviton Countdown Switch 10-20-30-60 min - Bathroom Timer

In this review of the Leviton Countdown Switch, the verdict is straightforward: this is a practical, higher-capacity timer switch for anyone who wants a reliable set-and-forget solution for bathroom fans and more. The five-button layout with 10, 20, 30 and 60 minute presets plus a manual off gives predictable control, and the switch's larger load capacity makes it suitable for common exhaust fans and heavier fixtures. Installation is straightforward for anyone comfortable with basic wiring, and the shallow design helps it fit into most wallboxes.

Key Features

• Countdown presets: Four preset time buttons let you pick 10, 20, 30 or 60 minutes quickly so fans and lights turn off automatically when the cycle ends.
• Higher load capacity: Rated for 600W LED/CFL and up to 1800W incandescent, it handles larger fixtures and many exhaust fans without overload worries.
• Flexible wiring options: Works as a single pole, in multi-way with the DD0SR companion, or as a multi-timer using two DT260 units for expanded control.
• Compact, Decora-style design: Shallow profile fits most wallboxes and matches Decora devices, with optional DTKIT faceplates to change color.
• Practical applications: Suitable for bathroom exhaust fans, porch and landscape lighting, heat lamps, pool pumps and other intermittent loads needing timed control.

Who It's For

The Leviton Countdown Switch is ideal for homeowners who want to automate bathroom exhaust fans, heat lamps and similar intermittent loads without running a separate timer device. It appeals to DIY installers who are comfortable handling a neutral wire and basic screw or connector wiring, and to those who need a higher wattage rating than typical low-power timers.

It is not the best choice when the controlled light is the only light source in a space, since the manufacturer advises against that use. Also, if you need a wireless smart integration or app control, look elsewhere; this is a reliable manual-countdown solution rather than a networked device.

Pros & Cons

Pros

• Works well for bathroom fans and larger fixtures thanks to its generous load ratings.
• Easy to install in standard wallboxes due to its shallow design and clear wiring requirements.
• Simple preset buttons make timed operation intuitive and consistent for household use.
• Compatible with Decora styling and optional faceplates for color matching.

Cons

• Requires a neutral wire, so older two-wire installations may need an electrician to update wiring.
• No smart connectivity or remote control options; it is a manual countdown switch only.
