General

A Manual Transfer Switch (MTS) is a critical electrical device designed to provide reliable power supply for essential circuits. It serves as a secure bridge between two independent power sources, typically the utility power (main source) and a generator (backup source).

1. Safe Power Source Transfer

The primary function is to manually shift the electrical load from a failed or de-energized main power source to a live backup source. This ensures that critical systems and equipment can continue operating without prolonged interruption.
2. Complete Electrical Interlocking

A key safety mechanism ensures that both power sources can never be connected simultaneously. This prevents back-feeding, which could cause severe short circuits, damage equipment, and pose a serious hazard to utility workers.
3. Isolation and Operator Control

It features a clear "OFF" or "Open" position, allowing for complete physical isolation of the load from both sources. This enables safe maintenance and servicing.
Operation is direct and intentional, with clearly marked positions (e.g., "Line 1," "Line 2," "Off"). This manual, non-automated process gives operators full control and eliminates the risk of unintended automatic switching.
