Dpdt switch 
A Double Pole Double Throw Switch (DPDT switch) is a type of electrical switch used to control two separate circuits at the same time, and each circuit can connect to one of two outputs.
Basic Idea

DPDT = Double Pole Double Throw
Double Pole: controls 2 independent circuits
Double Throw: each circuit can connect to 2 different terminals
So it acts like two SPDT switches operated by one lever.
Terminal Layout

A typical DPDT switch has 6 terminals:
1   4

2   5

3   6

2 & 5 → common terminals
1 & 4 → first position connection
3 & 6 → second position connection
How It Works

Position 1
2 → 1

5 → 4

Position 2
2 → 3

5 → 6

Common Uses

DC motor direction control (forward / reverse)
Polarity reversing circuits
Switching between two power sources
Audio signal routing
Electronic projects and robotics
Example: Motor Direction Control

A DPDT switch can reverse the polarity of a DC motor, which changes the rotation direction.
