Why Smart Switches Need a Capacitor? (Here''s the Answer)
When used in a smart switch, a capacitor helps to provide a better switching performance by providing additional power when there is an increase in demand from the system. Additionally, they can help reduce power surges, which can damage the system, and can help reduce the noise generated by the system when it is in operation.
