Broan-NuTone Three-Rocker Wall Switch
The Broan-NuTone P3RW provides three independent rockers in a single wall unit. It is designed to control multiple bathroom devices such as a fan, light, heater, or nightlight from one compact control. This makes it suitable in bathrooms with combined exhaust, lighting, and heating needs. The switch is rated for standard 120V operation and supports a total of up to 15 amps per switch, fitting a typical single-gang wall box. The tri-rocker configuration offers straightforward, one-location control for quicker adjustments during showers or baths.
Leviton Countdown Timer DT130-1LW
The Leviton DT130-1LW is a 5-10-15-30 minute countdown timer switch with no neutral required. It automates fan and lighting loads by presetting a countdown that turns off devices when time expires. Its shallow design accommodates most wallboxes, and it supports up to 15A resistive loads and up to 9.8A for fans/motors. This model uses the Green Flex Sleeve for grounded installation when a neutral is unavailable, while still offering a safe grounding option if a neutral is present.
Leviton Countdown Timer DT160-1LW
Leviton DT160-1LW expands countdown options to 10-20-30-60 minutes with the same no-neutral requirement approach as the DT130-1LW. It supports a wide range of loads including LED/CFL lighting and various fan/motor configurations, making it a flexible option for larger bathrooms or homes with mixed lighting and ventilation needs. The timer’s installation mirrors other single-pole timers and relies on a ground connection for safety where required.
Broan-NuTone BHFLED80 PowerHeat Bathroom Unit
The Broan-NuTone BHFLED80 blends an exhaust fan, a heater, and a dimmable LED light into one integrated unit. With an 80 CFM exhaust capability and 1.5 sones, it efficiently removes moisture while providing warmth and illumination. The integrated dimmable LED supports color temperature options, allowing warm, bright, or daylight lighting to suit different bathroom tasks. The design emphasizes a cohesive, space-saving solution with modern aesthetics.
ENERLITES Countdown Timer Switch (1-30 Min)
The ENERLITES 1-30 minute countdown timer switch provides flexible control for fans and lights with a neutral wire requirement. It features six preset timing options and a manual override, making it suitable for bathrooms where you want automatic shutoff after a set period. The unit is UL listed and designed to replace standard in-wall switches, delivering energy-saving benefits alongside predictable ventilation and lighting control.
Leviton Humidity Sensor With Separate Light
This Leviton model combines a humidity-sensing fan control with a separate light switch. The humidity sensor automatically activates the exhaust when moisture rises, while a dedicated light switch handles vanity lighting or a mirror light. It supports a range of load types with flexible installation, including non-neutral configurations, and emphasizes moisture control alongside lighting convenience for bathrooms with variable humidity.
BN-LINK Mechanical Countdown Timer
The BN-LINK in-wall timer provides a mechanical solution with up to 60 minutes of countdown. It installs in place of a standard wall switch and is compatible with most single or multi-gang decorator or toggle plates. This is a straightforward option for those seeking a simple, durable timer without electronic components that might fail in humid bathroom environments.
ENERLITES 2-Pack Countdown Timer Switch
The ENERLITES HET06A model offers a 1-5-10-15-20-30 minute timer with a neutral wire requirement in a two-pack. This configuration is suitable for households needing multiple bathroom or utility areas controlled by timed shutoff. The inclusive design supports a variety of loads, helping to manage ventilation and lighting across rooms with consistent performance and safety compliance.
Buying Guide: Key Considerations For Selecting The Right Switch
