Combined together, switching surges are the overcurrent/overvoltage spykes that are experienced in the highly inductive circuits at the time of sudden interruption I.e. switching period. As the magnetic field about the inductive conductor collapses, a brief very high voltage can be generated at that point.

In New Zealand, the outlets have switches on them so you can leave the piece of equipment plugged in but switch off the surge of electricity. Contrary to the US, the switch is down which means it is “ON”. A lot of New Zealand power outlet switches have a red mark on them it indicates the power is on.

A switching BEC is a sort of voltage converter. It takes pulses of high voltage and stores the energy in an inductor, and releases it at a lower voltage. Much more efficient so less heating of the BEC circuit.

SWITCH MODE TRANSFORMERS. Switch mode transformers (also known as switch mode power supply transformers and SMPS transformers) are using in a regulated power supply and function to step up or step down voltage or current, and/or provide isolation between the input and output side of a switch mode power supply.

Easier to Identify Switched Outlets Electricians may position the outlet in an upside-down position so that you can quickly identify the switch-controlled receptacle. Since it stands out visually to most people right away – it provides convenience to the occupants to easily remember which outlet is switch controlled.
