An object that will stop the flow of a current is called a switch.
what switches a current of electricity if it gets to high is that it overloads a system (which is called a surge (if sudden)) also if you do it manually it is the disruption in the circuit that stops the flow of electricity entirely.
Battery
A switch is a device that stops and starts current flow in a circuit.
A substance that lets electricity flow through it is called a conductor (or sometimes, to be more explicit, it is called an electrical conductor). Substances which do not permit the flow of electricity are called insulators.
An electrical current.
Rubber. Or an insulator.

switch...this break the flow of electricity, from a circuit
Switches.
Battery
The flow of electricity is called the current. It is measured in Amps (I).Current is the flow of electrons around an electrical circuit.
An object that does not allow electricity to flow through easily is an insulator. It is so hard that it often won't go through at all. Sometimes you find an exception, like lightening. There is nothing that electricity cannot flow through altogether.

Resistance. Where as in an electrical circuit there are resistors that restrict the flow of electricity
