In this note, we explain what switch power is, why it is a growing trend and what solutions are available.

In high-voltage applications, switched power refers to energizing or de-energizing entire circuits at main electrical distribution panel. Rather than individually turning off lights or outlets with breakers / switches, an entire area is designed to have power cut off at one central spot.
