🔷 What is a Dual Power Manual Changeover Switch?

A manual changeover switch (also known as a manual transfer switch or MTS) is an electrical device that allows users to safely switch power supply from one source to another.

Example:

• Source 1 → National Grid
• Source 2 → Generator / Backup Power

Instead of directly connecting both sources (which is extremely dangerous), the switch ensures:

• Only one source is active at a time
• No backflow or short circuit occurs
• Safe power transition is maintained

The TOMZN TO219G is specifically engineered for single-phase systems, making it perfect for:

• Homes with heavy load
• Offices
• Shops & commercial buildings
• Light industrial setups

🔷 Installation and Usage Guide

Installing the TOMZN TO219G Manual Transfer Switch should always be performed by a qualified and certified electrician to ensure safety and compliance with local electrical codes in Bangladesh. Here’s a general overview:

1. Mounting: Securely mount the switch inside a suitable electrical enclosure or distribution board using its 35mm DIN rail clip or screw mounting holes.
2. Wiring: Connect the primary power source (e.g., utility grid) to one input terminal set and the secondary power source (e.g., generator) to the other input terminal set. Ensure the load wires are connected to the output terminals. Always follow the provided wiring diagram carefully.
3. Grounding: Ensure proper grounding for both the switch and the entire electrical system.
4. Testing: Once installed, conduct thorough testing to verify correct operation and safety before putting the system into full service.
5. Operation: To switch power sources, simply toggle the robust handle to the desired position (Source 1 or Source 2). The mechanical interlock prevents both sources from being active simultaneously. Always ensure all critical loads are off before switching to minimize transient spikes.
