WebSwitch disconnectors perform this function, cutting off the electricity supply to power down a length of the electrical circuit so it can be serviced. Fused switch disconnectors are a type of isolator, a standard electrical safety device, but they differ from other varieties in combining isolating and current switching functions. Web31 jan. 2024 · There are two types of power supplies that can be designed into a circuit board; isolated and non-isolated. Although isolation can refer to separating the power supply parts from the rest of the design on the PCB, it usually refers to isolation between the inputs and outputs of the power supply itself.
