Question

question 9 points 2
which of the following is true about the 3-wire control method of 2-way switching?

the phase is connected to pin 2 of both the switches.

the one end of the light bulb is connected to pin 1 of both the switches.

the common terminal of both the switches is short - circuited.

the neutral line is connected to pin 1 of both the switches.

Explanation:

To determine the correct statement about the 3 - wire control method of 2 - way switching, we analyze each option:

• Option 1: In the 3 - wire control method of 2 - way switching, the phase is connected to pin 2 of both switches. This is a correct characteristic of this switching method.
• Option 2: The light bulb's connection is not to pin 1 of both switches in this method, so this is incorrect.
• Option 3: The common terminals of the two switches are not short - circuited in the 3 - wire 2 - way switching control method, so this is incorrect.
• Option 4: The neutral line is not connected to pin 1 of both switches in this method, so this is incorrect.

Answer:

The phase is connected to pin 2 of both the switches.
