An MCB-type changeover switch is a modular, DIN-rail mounted device designed to safely transfer a building's load between two power sources, such as the utility grid and a generator. It features a three-position (I-O-II) center-off mechanism for secure, manual switching, ensuring no direct connection between sources. Available in double-pole (DP) for single-phase or four-pole (FP) for three-phase systems, these switches provide overload and short-circuit protection in a compact form.

Sheet metal switchgear changeover switches are industrial-grade electrical devices housed in durable metal enclosures, primarily used to safely transfer electrical loads between two power sources, such as a main utility line and a backup generator.
