An "air break switch' is a switching device that uses air the dielectric. Air break switches can be single pole or 'gang operated', and can be operated manually (using either a handle/ratchet mechanism or an insulated 'hook stick' made either of wood or fiberglass). Air break switches are designed for switching under load, but there is often a noticeable arc associated with switching. Air break switches can be found either in substations or out on the distribution system - either pole top or in pad-mounted metal enclosures.
A breaker is a switching device that operates automatically and is specifically intended to interrupt short circuit currents (in addition to ordinary load currents). Circuit breakers can be designed using air, oil, vacuum, or SF6 gas as the dielectric. Circuit breakers are only found in substations.
A recloser is a lot like a circuit breaker both in function and also the choice of dielectric. Reclosers typically have less short circuit interrupting capacity than breakers, but they are designed to automatically reclose to restore the interrupted circuit. The reason for that is that most (typically, more than 80% of the faults on overhead distribution circuits are self-clearing (tree branches, small animals, etc) and can be restored if the circuit is allowed to remain de-energized for 10-15 seconds so that the ionized air in the vicinity of the fault can dissipate. Reclosers are much less expensive than breakers.
A sectionalizer is a device that is applied out on a distribution circuit that is intended to determine that a fault is located downstream of the recloser; the principle of operation is that once the sectionalizer makes the determination that the problem is downstream, it can open, and then an upstream reclosing device (either a recloser or a circuit breaker) can automatically reclose to restore service to those loads that are upstream of the sectionalizer. A sectionalizer doesn't have any current interrupting capability, but instead relies on the upstream device to interrupt fault current.
A disconnector is simply a device that is used to disconnect a load. It can be an air break switch, or it could be a circuit breaker. The name implies the function and is not necessarily descriptive of the device itself.

What is the difference between a load break switch and an air break switch?
The main difference is that air break switches lack a mechanism for suppression and load break switches do have them. They are both disconnect switches but have different uses.
What is difference bitween air break switch and load break switch?
Both are types of isolators of a power circuit. Load break switch is an isolator where circuit can be isolated on load. The quenching media could be air, oil or gas..... Air break switch is type isolator where isolation takes place in the air itself. (break contacts are not immersed in oil, gas ...) But whether these isolators can be opened on load or not can be said only by looking at the desgin data. Some isolators are designed to open and close on load.
Which insulator does a switch use to cut off the current in a circuit?
A switch uses an insulator called an "air gap" to cut off the current flow in a circuit. When the switch is turned off, it creates a physical break in the circuit, preventing electricity from passing through.
What is the difference between an air break switch and an isolator?
An air-break link (ABL) switch is designed to interrupt normal load currents (but not fault currents). In order to do so, they usually incorporate some form of very simple arc-extinguishing feature.An isolator switch, on the other hand, is not designed to interrupt current, but to isolate equipment after that equipment has been disconnected (e.g. by opening a circuit breaker).

What is the of a switch?
The function of a switch is to break and connect the flow of electricity.
Calling a function from switch in C?
Yes, you can call a function from within a switch statement in C. switch (i) { case 0: function1(i); break; case 1: function2(i); break; default: function3(i); break; } When the function returns, you will still be in the switch statement.
How can we use characters in the switch statements to select the cases java?
Switch statements in Java can only use integer values. This means that we can switch on char values (because chars are simply ints with a different output type), but we can not switch on Strings or any other objects. The following examples are both valid in Java. // switch 1 int x = 1; switch(x) { case 0: break; case 1: break; default: break; } // switch 2 char x = '1'; switch(x) { case '0': break; case '1': break; default: break; }
