 ⚡ Changeover Switch Kya Hota Hai? Ghar Mein Changeover Switch Ki Wiring Kaise Kare? Complete Guide in Hindi 2026

Introduction

Aajkal lagbhag har ghar mein inverter ka istemal kiya jata hai. Jab bijli chali jati hai, tab inverter ghar ke fan, light aur kuch zaroori appliances ko chalata hai. Lekin ek sawal bahut logon ke dimaag mein aata hai – Mains supply aur inverter ke beech switching kaise hoti hai? Iske liye jis device ka use kiya jata hai, use Changeover Switch kehte hain.

Kai log bina changeover switch ke direct wiring kar dete hain, jo dangerous ho sakta hai aur inverter ko bhi damage kar sakta hai. Is article mein hum detail mein samjhenge ki changeover switch kya hota hai, kaise kaam karta hai, kitne type ke hote hain, wiring kaise ki jati hai aur kaun si safety ka dhyan rakhna chahiye.

Changeover Switch Kya Hota Hai?

Changeover Switch ek electrical switching device hai jo do alag-alag power sources ke beech supply ko transfer karta hai.

Ghar mein aam taur par do power sources hote hain:

Electricity Board (Mains Supply)

Inverter Supply

Changeover switch in dono supplies mein se kisi ek ko load ke saath connect karta hai.

Simple language mein:

Changeover switch decide karta hai ki ghar ki supply mains se aayegi ya inverter se.

Changeover Switch Kaise Kaam Karta Hai?

Maan lijiye aapke ghar mein bijli aa rahi hai.

Is condition mein:

Mains → Changeover Switch → Load

Ab agar bijli chali jaye to aap switch ko inverter position par kar dete hain.

Tab:

Inverter → Changeover Switch → Load

Is process mein dono supplies ek saath connect nahi hoti. Isi wajah se inverter aur mains ek dusre se protected rehte hain.

Changeover Switch Ki Zarurat Kyu Padti Hai?

1. Safety Ke Liye

Galat wiring se short circuit aur electric shock ka risk badh jata hai.

2. Inverter Protection

Mains aur inverter ko ek saath connect hone se bachata hai.

3. Easy Switching

Ek source se dusre source par easily shift kar sakte hain.

4. Maintenance Ke Liye

Repair aur servicing ke samay supply ko safely disconnect kiya ja sakta hai.

5. Reliable Power Supply

Power cut ke time ghar ke important loads ko chalu rakhta hai.

Changeover Switch Ke Types

1. Manual Changeover Switch

Ye sabse common type hai.

Features:

Haath se operate karna padta hai

Cost kam hoti hai

Installation simple hoti hai

Gharon mein zyada use hota hai

Advantages:

Sasta

Aasan maintenance

Long life

Disadvantages:

Manual operation ki zarurat padti hai.

2. Automatic Changeover Switch

Ismein bijli jaate hi supply automatically inverter ya generator par transfer ho jati hai.

Features:

Automatic operation

Fast switching

Human intervention ki zarurat nahi

Advantages:

Convenience

Fast response

Better protection

Disadvantages:

Mehenga hota hai

Installation complex hoti hai.

DP Changeover Switch Kya Hota Hai?

DP ka matlab hota hai:

Double Pole

Ye Phase aur Neutral dono ko ek saath switch karta hai.

DP changeover switch single-phase homes mein zyada use kiya jata hai.

Applications:

Homes

Shops

Small offices

Inverter systems

TPN Changeover Switch Kya Hota Hai?

TPN ka matlab:

Triple Pole and Neutral

Ye 3-phase systems ke liye use hota hai.

Applications:

Industries

Commercial buildings

Large villas

Factories

Changeover Switch Ki Rating Kaise Select Kare?

Galat rating ka switch use karna dangerous ho sakta hai.

Small Home

16A se 32A

Medium Home

40A se 63A

Large House

63A se upar

Current Kaise Calculate Kare?

Formula:

Current = Load ÷ Voltage

Example:

Load = 3000 Watt

Voltage = 230 Volt

Current = 3000 ÷ 230

Current ≈ 13 Ampere

Is case mein 16A ya 32A changeover switch suitable rahega.

Ghar Mein Changeover Switch Ki Wiring Kaise Kare?

Required Materials

Changeover switch

MCB

Wires

Screwdriver

Tester

Insulation tape

Step 1

Main supply ko OFF kare.

Step 2

Mains supply ko changeover ke input terminal mein connect kare.

Step 3

Inverter output ko second input terminal mein connect kare.

Step 4

Output terminal ko load side ke MCB se connect kare.

Step 5

Neutral wiring ko proper terminal ke according connect kare.

Step 6

Connections ko double-check kare aur power ON kare.

Basic Wiring Concept

Position-1

Electricity Board Supply

Mains → Changeover → Load

Position-2

Inverter Supply

Inverter → Changeover → Load

Practical Example

Maan lijiye aapke ghar mein:

4 Fans

8 LED Lights

TV

Wi-Fi Router

Power cut hone par aap chahte hain ki ye sab inverter se chale.

Aap ek 32A DP Changeover Switch install kar sakte hain.

Jab bijli aa rahi hogi:

Mains Supply ON

Jab bijli chali jayegi:

Changeover ko inverter position par shift kar denge.

Pura essential load chalu rahega.

Changeover Switch Install Karne Ke Fayde

1. Better Safety

Short circuit aur back-feeding ka risk kam hota hai.

2. Inverter Protection

Inverter damage hone se bachta hai.

3. Easy Operation

Switching simple ho jati hai.

4. Low Maintenance

Maintenance bahut kam hoti hai.

5. Long Life

Quality switch kai saalon tak chal sakta hai.

Common Mistakes Jo Nahi Karni Chahiye

1. Wrong Rating Use Karna

Chhote switch par zyada load nahi dena chahiye.

2. Loose Connections

Loose wiring heating aur fire ka reason ban sakti hai.

3. Earthing Ignore Karna

Proper earthing zaroori hai.

4. Low Quality Product

Cheap products jaldi kharab ho jate hain.

5. Wrong Wiring

Galat connection inverter aur appliances ko damage kar sakta hai.
