• C. It is a press button switch.
• D. It is a two way switch.

Answer 1

The correct option is B

It is a double pole switch.

It is a double pole or DP switch. It is an electrical switch which has two blades with their contacts for simultaneous opening or closing both sides of a circuit. A double pole switch connects an input terminal to one of two output terminals in the circuit. Thus, it has three terminals. One of the terminals is called the common terminal. The other two terminals are often called as A and B.
