Smart Switches / Capacitor
Does the capacitor consume electricity?
Short answer: It may allow a very small current for the smart switch circuit, but the consumption is normally very low.
Explanation
The capacitor used with a no-neutral smart switch helps the switch obtain stable power through the lighting circuit. The current involved is very small and is mainly for powering the switch electronics. In normal home use, the energy impact is usually negligible compared with the lighting load. The main purpose of the capacitor is stability, not energy saving.
Common mistakes
- Thinking the capacitor is a battery
- assuming it powers the light
- removing it to save electricity.
Troubleshooting / next steps
- Keep the capacitor installed if the product requires it for stable operation.
