Leviton Countdown Timer Switch, DT104-1LW
The Leviton DT104-1LW is a single-pole countdown timer designed for lights, heaters, and exhaust fans. It offers four preset time buttons (30 minutes, 1 hour, 2 hours, and 4 hours) and automatically turns off when the timer expires. Installation is straightforward, with a shallow design that fits most wall boxes. The device supports up to 600W LED/CFL and 1800W incandescent loads, along with ½ HP/9.8A for motors or fans and a 15A resistive rating. It includes a Green Flex Sleeve to wire to ground when no neutral is present, or you can remove the sleeve to connect to a neutral if available. A ground wire is required.
Why choose this model: It provides a compact, easy-to-install solution for controlling heating or ventilation appliances without requiring a neutral wire, making it suitable for many older homes or retrofit projects. The four preset options help automate common routines and reduce standby energy use.
BN-LINK 60-Minute In-Wall Countdown Timer
The BN-LINK timer is a mechanical, in-wall countdown timer designed for a straightforward install in place of a standard wall switch. It provides up to 60 minutes of operation with no neutral wire required. The timer is compatible with single-pole electrical configurations and fits standard wall plates, making it a practical choice for bathrooms or utility areas where you want to automatically shut off lights or ventilation after a set period.
Why choose this model: It offers a simple, robust option for quick installations. The no-neutral requirement broadens compatibility with many older homes, and its compact form suits tight spaces behind a standard wall plate.
Leviton DT130-1LW Countdown Timer
The Leviton DT130-1LW is another No-Neutral countdown timer from Leviton, featuring 5-, 10-, 15-, and 30-minute presets plus a 60-minute option. This model is designed for single-pole applications and can control bathroom fans and household lights. Its shallow design matches the DT104-1LW’s installation profile, simplifying retrofits in crowded wall boxes. It supports similar electrical loads: LEDs, CFLs, incandescent/heating elements, and motorized devices up to ½ HP/9.8A for fans and motors, with a 15A resistive rating.
Why choose this model: The extended preset range gives more flexibility for different rooms and activities, such as bathroom ventilation after a shower or gradual lighting for bedtime routines.
GE SunSmart Digital In-Wall Timer, 32787
The GE SunSmart 32787 timer includes advanced features like sunrise/sunset-based programming to align your schedules with natural daylight. It supports up to seven ON/OFF programs per week and offers a random security feature that can adjust settings by up to 30 minutes to simulate activity when you’re away. This switch is designed for neutral-wire installations and suits both LED/CFL and incandescent lighting, as well as other fixtures connected to a standard single-pole circuit. It’s a strong option for homes looking to automate daily routines with a bit of “live-in” security.
Why choose this model: Its solar-timed programming and security feature provide a more dynamic setup for households seeking automation that adapts to daily light changes and adds a layer of realism when away from home.
GE Push-Button Countdown Timer, 15318
The GE 15318 is a push-button countdown timer switch designed for environments without a neutral wire. It supports six preset durations: 5, 15, 30 minutes, and 1, 2, or 4 hours. It’s suitable for lights, exhaust fans, or heaters in older homes or new constructions that lack a neutral conductor in the switch box. A standard wall plate is included to ensure easy replacement in single-gang installations.
Why choose this model: It provides a classic push-button interface with a broad preset range, making it a practical choice for retrofits where wiring is limited or older wiring configurations remain in place.
Buying Guide
- Power and load compatibility: Check each timer’s wattage and motor-load ratings to ensure it can safely control your heater, fan, or light. Heaters and motors typically require different considerations than lighting circuits.
- Neutral wire requirements: Some models require a neutral wire, while others do not. If your wall box lacks a neutral, consider the DT104-1LW, DT160-1LW, or GE 15318 options that support no-neutral installations.
- Preset range and programming: Decide whether you prefer quick presets (5–30 minutes) or longer ranges (60 minutes or more). Some models also offer weekly programming and sunrise/sunset features for broader automation.
- Installation ease: Look for a shallow design and compatibility with standard wall plates. A compact form factor simplifies retrofits in crowded or older wall boxes.
- Security and automation features: If you want automated routine simulation when away from home, consider models with randomization or timer-aware vacation features (like GE SunSmart).
- U.S. electrical standards: Ensure the device is UL-listed and rated for 120V operation common in American homes, and confirm load ratings align with your device (lights, fans, heaters, or small appliances).
When choosing, balance the need for precise timing with installation constraints and long-term reliability. For households with older wiring, models that do not require a neutral wire provide flexibility. For modern homes, timers with more programming options and sunrise/sunset integration can maximize energy savings and convenience.
