Buying Guide
Key considerations when choosing a bathroom fan light and heater switch:
- Load capacity: Ensure the device supports the combined amperage of your fan, light, and heater. Look for 15A per switch or higher where needed.
- Neutral requirements: Some timers require a neutral wire; others offer no-neutral or green-sleeve grounding options. Confirm your wall box wiring before installation.
- Form factor: Decide between triple-rocker units or multi-function timer switches. Consider plate style, ease of cleaning, and compatibility with existing wall plates.
- Installation: Simple, shallow designs ease retrofits. Check wall box depth and whether a single gang is sufficient for your configuration.
- Programmable vs mechanical: Programmable timers provide precise control and energy saving; mechanical timers offer simplicity and reliability without electronics.
- Compatibility: Verify compatibility with LED, CFL, incandescent, and motor loads to avoid nuisance tripping or reduced performance.
