How many lines can a DPDT switch cut?

A Double Pole Double Throw (DPDT) switch is designed to control two separate circuits simultaneously within one switch unit. Each pole manages a different circuit, while "double throw" indicates that each pole can connect to one of two output lines. Therefore, when a DPDT switch is activated, it can cut or interrupt the flow of electricity in two different lines.

Each of the two poles can connect to one of two outputs, which means that when the switch is thrown, it can effectively redirect currents and cut off connections in both of those lines. This gives it the capability to cut two lines, making the answer accurate in the context of how many circuits it can manage and interrupt.
