A double pole switch can be used in either a 240V application where you'll need to disconnect 2 "hot" lines, or it is useful when switching a light from 3 different switches.
Disadvantage?
I suppose it could be a little confusing to face all those contacts on a double pole switch.

What is the difference between single pole mcb and double pole mcb?
A single pole circuit breaker can protect one hot wire to a given load where as a two pole circuit breaker can protect two hot wires to a given load. In the North American system this would equate to 120 volts on a single pole circuit breaker and 240 volts on a two pole circuit breaker.
On which line is the switch of electrical appliance connected?
A Switch on a domestic supply has always got to be on the LIVE part of that circuit. A double pole switch switches both the LIVE and NEUTRAL off together.
How do you select an MCB?
While selecting an MCB you have to check: 1) Current Rating; 2) Response Time; 3) Manufacturer; 4) Type of MCB (means single pole, double pole, three pole, four pole - it depends on the application); 5) Cost; 6) short circuit breaking capacity.

What is the purpose of a 30 amp double pole breaker in an electrical circuit?
The purpose of a 30 amp double pole breaker in an electrical circuit is to protect the circuit from overloading by shutting off the power if the current exceeds 30 amps.
What is the difference between a single pole switch and a double pole switch?
A single pole switch controls one circuit, while a double pole switch controls two separate circuits.
What is the purpose of a double pole 60 amp breaker in an electrical circuit?
A double pole 60 amp breaker in an electrical circuit is used to protect the circuit from overloading and short circuits by disconnecting power when the current exceeds 60 amps.
What is the appropriate double pole 30 amp breaker to use for a dryer installation?
The appropriate double pole 30 amp breaker to use for a dryer installation is a 30 amp double pole circuit breaker.
What does single pole and double pole mean on a twenty four vault circuit?
Single pole refers to a circuit breaker that interrupts the current flow of one hot wire, while double pole interrupts the current flow of two hot wires simultaneously. In a 240-volt circuit, a double-pole breaker is used to control both the hot wires, providing higher safety protection as both sides of the circuit are disconnected.
What is the purpose of a 20 amp double pole breaker in an electrical circuit?
The purpose of a 20 amp double pole breaker in an electrical circuit is to provide protection by simultaneously disconnecting both the hot and neutral wires in the circuit if there is an overload or short circuit, preventing damage to the circuit and reducing the risk of electrical fires.
