The wires that feed electricity to double pole switches tend to be larger than the wires that feed to single pole switches, as double pole switches are often used to control 240V circuits. here
See full version: Single Pole vs Double Pole Switches
The wires that feed electricity to double pole switches tend to be larger than the wires that feed to single pole switches, as double pole switches are often used to control 240V circuits. here
A double pole socket switches both the live and neutral to ensure safe isolation of the plugged in appliance.
The pole of a switch refers to the amount of separate circuits that switch can control. Single pole switches can control just one circuit and a double pole switch can control two circuits. So a double pole switch is almost like having two single pole switches, controlled by the same switch. more
In theory you would only have 1-2 permanent live feeds and 1+ load lives. There are a number of different ways to wire lighting or isolation circuits so there could be a number of different combinations.

Simply put, the common simple light switches you see in your home are single-pole switches. They operate one circuit and offer a standard on and off function. Double pole switches are generally used to control 240V circuits and operate higher demand appliances and motors.
A noteworthy feature of double pole switches is their four hot brass terminal and a ground terminal. This enables you to attach the switch to two pairs of power sources from a 240-volt circuit. more
This is a case of on-off vs isolation switching. Single pole switches work best for turning on and off a light fixture or appliance. However, for isolating a circuit, a double pole works better and mainly because it’s safer. [links]
