Connecting Two-Way Switch in Two Wire Configuration
This is the old-school method for a 2-way switch connection. For new installations, consider the 3-wire control method.
In the 2-way switch diagram, the live wire connects to the common terminal of the first switch. PIN1 & PIN2 of the first switch connect to PIN1 & PIN2 of the second switch. One end of the bulb connects to the common terminal of the second switch, and the other end connects to the neutral line of the AC supply.
Note: In the 2-wire control method, the light will be OFF when the switches are in opposite states, as shown below. It's like a game of switcheroo!

The condition of getting Output in ON condition is the same as the Ex-nor gate.
This newer, more efficient 3-wire method for 2-way switch connections is commonly used today.
In the diagram, the commons of both switches are short-circuited. PIN1 of both switches connects to the live wire, and PIN2 connects to one end of the lamp. The other end of the lamp connects to the neutral line of the AC supply.
Note: In the 3-wire method, the light is OFF when switches are in the same state, as shown below. here

Advantages and Disadvantages of these configurations
Advantages:
Allows control of any appliance from two different areas, regardless of the distance between them. Ideal for locations like staircases, large rooms, and bedrooms where control from multiple points is beneficial. Reduces the need to walk across dark areas to turn lights on or off, enhancing safety.
Disadvantages:
-Increased Wiring: Requires a significant amount of wiring, which can be more complex and costly to install. Diagnosing and fixing issues can be more challenging due to the additional wiring and switch points.
Conclusion:
In conclusion, the 3-wire method for 2-way switch connections is more efficient and commonly used today compared to the old 2-wire method. By understanding the differences and wiring techniques, you can effectively control lighting from two locations.
