Why Smart Switches Need a Capacitor? (Here''s the Answer)
Troubleshooting Tips for Smart Switches with Capacitors. Smart switches are an important part of many electrical systems and require capacitors to help regulate the flow of energy. Without capacitors, smart switches may not be able to provide the stability, switching performance, and power protection needed by the system.
Capacitor Basics: How do Capacitors Work?
As capacitors store energy, it is common practice to put a capacitor as close to a load (something that consumes power) so that if there is a voltage dip on the line, the capacitor can provide short bursts of current to resist that voltage dip.
Capacitor types
Capacitors are divided into two mechanical groups: Fixed-capacitance devices with a constant capacitance and variable capacitors. Variable capacitors are made as trimmers, that are typically adjusted only during circuit calibration, and as a device tunable during operation of the electronic instrument.. The most common group is the fixed capacitors.
