Changeover Switch Types: Complete Guide for Pakistan (2026)
Changeover switch types in Pakistan include manual DIN rail models, rotary change over switches, automatic transfer switches, and miniature transfer switches. For most homes, a 2 Pole manual changeover switch is the practical choice. For offices, clinics, shops, and factories, an automatic changeover switch is often safer because it shifts supply faster and with less room for human error.
If you have lived through a Lahore summer, a Karachi feeder trip, or winter load shedding in Faisalabad, you already know why this matters. Utility power goes off, the generator starts, and someone has to move the load from one source to the other. If the wrong switch is installed, the result is not just inconvenience. It can mean overheated contacts, nuisance trips, backfeed, or a dangerous panel.
This guide explains the main changeover switch types available in Pakistan, how to choose the right pole configuration, what sizes are commonly used, and what to check before you compare changeover switch price in Pakistan.
What Is a Changeover Switch?
A changeover switch transfers electrical load between two power sources, usually WAPDA and a backup source such as a generator, UPS, or solar inverter. Its job is simple: let only one source feed the circuit at a time.
In Pakistan, the change over switch is almost standard anywhere a generator or alternate supply is used. The right model depends on system size, phase arrangement, switching frequency, and whether you want manual control or automatic transfer.
Types of Changeover Switches
1. Manual DIN Rail Changeover Switches (YCBZ Series)
Manual DIN rail models are the most familiar choice in Pakistani homes. They sit inside the DB and are operated by hand. When WAPDA fails, you move the handle to the backup side.
Manual 2 Pole 63A is Rs.2,200 and manual 4 Pole 63A is Rs.4,500. If you are checking 63 amp changeover switch price in Pakistan, these are the figures to keep in mind.
Best for: Homes, small offices, and users who do not mind switching by hand.
2. EP Rotary Changeover Switches
A rotary changeover switch uses a turning handle instead of the usual lever. The EP series suits buyers who want a manual change over switch with a more panel-grade feel.
Best for: Offices, commercial boards, workshops, and industrial panels.
3. Automatic Transfer Switches (ATS)
An automatic transfer switch removes the human delay. The moment main supply fails, the ATS transfers the load to the backup source.
- ATS 2P YCQR 63A — Rs.8,250
- ATS 4P YCQR 63A — Rs.15,500
- ATS 2P YCQ4 100A — Rs.5,500
- ATS 2P YCQ1B
- ATS 4P YCQ1B
- ATS 4P 200A-630A
Best for: Businesses, data equipment, medical loads, offices.
4. Miniature Transfer Switches (MTS)
MTS units are compact transfer devices for smaller sections of load, useful in AC and DC applications especially solar and battery systems.
How to Choose: Poles and Phases
| Your System | Poles Needed | Common Choice |
|---|---|---|
| Single phase, no neutral | 1 Pole | Rare in Pakistani homes |
| Single phase, with neutral | 2 Pole | Most common house setup |
| Three phase, no neutral | 3 Pole | Selected motor loads |
| Three phase, with neutral | 4 Pole | Best for most commercial |
Manual vs Automatic: Which Should You Pick?
Choose manual if budget is tight and load is not critical. Choose ATS if power interruptions are frequent or load cannot tolerate delay.
| Model | Poles | Amps | VA Protection | Price |
|---|---|---|---|---|
| ATS Budget | 2 | 100A | No | Rs.5,500 |
| ATS Premium | 2 | 63A | Yes | Rs.8,250 |
| ATS Premium | 4 | 63A | Yes | Rs.15,500 |
Ampere Rating Guide
| Home/Office Size | Typical Load | Recommended Rating |
|---|---|---|
| 1-2 bedroom apartment | 10-20A | 63A changeover |
| 3-4 bedroom house | 20-40A | 63A changeover |
| Small office | 30-50A | 63A-100A |
| Large office/shop | 50-80A | 100A changeover |
| Factory/commercial | 100A+ | 125A manual or ATS |
Common Mistakes to Avoid
Using ordinary breakers as a homemade transfer arrangement is dangerous. Undersizing, ignoring neutral switching, and choosing only on headline price in Pakistan without checking build quality are common errors.
