Broan-NuTone P3RW Three-Rocker Switch For Bathroom Exhaust Fan
The Broan-NuTone P3RW provides three separate rocker switches in a single-gang assembly, enabling control of a fan, light, heater, or nightlight from one location. It is rated for standard 120V 60Hz circuits with up to 15 amps per switch, allowing multi-use by combining loads within the switch’s capacity. Installation fits a standard single-gang electrical box. The physical triple-rocker form is useful where you want consolidated control without additional wiring runs. This model does not include time-delay functionality; it focuses on consolidated manual control for multiple bathroom devices.
GE Push-Button Countdown Timer Switch 5-15-30 Min/1-2-4 Hr
This GE push-button timer offers six preset countdown durations and a simple push-button interface. It does not require a neutral wire, which makes it suitable for older homes where neutral wiring may be absent. The device is intended to replace a single-pole switch and is compatible with lights, exhaust fans, and heaters within the switch ratings. The included wall plate supports quick single-gang installation. The preset approach is straightforward for users who want timed operation without programming, and it automatically turns off loads after the selected interval.

The Leviton DT104-1LW provides four preset time buttons and supports a wide range of loads including LED/CFL, incandescent, halogen, and motors up to ½ HP or 9.8 amps. Its shallow profile suits tight wall boxes. A notable wiring feature is the Green Flex Sleeve, which allows wiring to ground when no neutral is present or removal to connect to a neutral if available. The unit is designed for single-pole installations and is rated for common household loads. It automates fan or heater operation and returns to off at the end of the selected countdown.
GE SunSmart Digital In-Wall Timer With Sunrise/Sunset
The GE SunSmart digital timer offers advanced scheduling, including weekly programs and a sunrise/sunset adjustment that updates across the year for your region. It supports daily on/off programming with random security offset and can replace single-pole or three-way switches if a neutral is present. Its digital nature makes it suitable for automation of permanently installed fixtures and heater circuits within the device’s electrical ratings. This is a programmable option for users who need repeated schedules, vacation simulation, or time-based control beyond simple countdowns.
TG 1-Hour Countdown Timer Switch For Fans And Heaters
The TG 1-Hour Countdown Timer offers six selectable intervals from 1 to 60 minutes and includes a manual on/off override. It features an LED indicator that flashes to confirm the timer setting and then turns off while the load runs. No neutral wire is required for installations that lack a neutral conductor. This model targets simple timed control scenarios for bathroom fans, lights, and heaters, adding an energy-saving auto-off function to prevent leaving devices on accidentally.
Buying Guide: How To Choose The Right Wall Heater Switch
Selecting the correct wall heater switch depends on wiring, load type, control style, safety, and installation constraints. Below are key considerations and comparison perspectives to guide a purchase.

Wiring And Compatibility
- No Neutral Required: Devices that do not need a neutral (GE Push-Button, Leviton with flex sleeve option, TG) are easier to install in older homes where only hot and ground are present. Confirm your wall box wiring before purchase.
- Neutral Required: Programmable or digital timers often need a neutral for power (GE SunSmart). If you have neutral available, these offer advanced features but require compatible wiring.
- Load Ratings: Check amp and horsepower ratings. For heater circuits and fan motors, ensure the switch supports the continuous load (e.g., 15A resistive, ½ HP motor ratings where listed).
Control Type And User Needs
- Manual Multi-Device Control: Multi-rocker switches like Broan-NuTone centralize control for fan, light, and heater without automation.
- Countdown Timers: Push-button and preset timers (GE Push-Button, TG, Leviton) are ideal for short-term operation—bath fans or heater zones where auto shut-off is needed.
- Programmable Timers: Digital programmable timers (GE SunSmart) suit repeat schedules, vacation modes, or sunrise/sunset features for lighting and heater control tied to daylight.
Installation And Physical Fit
- Gang Size: Confirm single-gang vs multi-gang compatibility. Most shown units fit single-gang boxes; multi-rocker condenses functions into one gang.
- Box Depth: Shallow designs (Leviton) help when wall boxes are tight or have backfill/insulation close to terminals.
- Wall Plate Options: Some units include a wallplate for immediate replacement; others fit standard decorator plates.
Safety And Electrical Compliance
- UL/ETL Listings: Choose switches with recognized safety listings for residential electrical applications.
- Continuous Load Considerations: Heaters are continuous or high-draw devices. Confirm the switch rating and local code for controlling permanent heater installations. In some cases, relay or contactor control is preferred for high-current heater loads.
- Motor Loads: Fans and blower motors may require higher inrush current handling; check motor amp and horsepower ratings.
Energy Savings And Convenience
- Auto-Off Functionality: Countdown timers prevent leaving heaters or fans on, saving energy and reducing wear.
- Scheduled Operation: Programmable timers allow tailored schedules and security features to simulate occupancy.
- Consolidated Controls: Multi-rocker switches minimize wall clutter and centralize control for zones combining heater, fan, and light.
Feature Trade-Offs And Use Cases
- Simplicity vs Flexibility: Preset countdowns and mechanical timers are simple, reliable, and often do not need a neutral. Digital timers offer flexibility but require extra wiring and setup.
- Control For Multiple Devices: Multi-rocker switches handle separate devices without timers; pair with a timer on the heater circuit if timed control is desired.
- RV Or Specialty Heaters: For water heater or RV-specific switches, choose purpose-built models (not included above) designed for those systems and load types.
Installation Tips
- Turn off power at the breaker before replacing or installing switches.
- Verify circuit amperage and match switch ratings; use a dedicated circuit for fixed high-draw heaters when required by code.
- When neutral is absent and a device needs neutral, consult an electrician—alternatives include neutral-less models or adding a neutral conductor.
- Follow manufacturer wiring diagrams; ensure ground connection where required for safe operation.
Use the factors above to align the chosen switch with the intended heater or fan load, the existing wiring, and the desired control behavior. Each product reviewed offers a specific balance of functionality—multi-device control, simple timed shutdown, programmable schedules, or compact installation—so prioritize the features most relevant to your application.
