Most typically, the most common and easiest-obtainable protective device is - a fuse. A fuse is such a device that is designed to break the circuit if certain conditions are met (typically a level of voltage, current, or a combination of the two).
A fuse is the simplest protective device for over current in an electric circuit.

A voltmeter is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
A switch is a device that is used to open and close an electrical circuit that is is connected into.
A battery is the device that creates a potential difference in an electric circuit. It establishes an electric field within the circuit that allows charges to move from the positive terminal to the negative terminal, creating an electrical current.

Remote-Control Circuit. Any electrical circuit that controlsany other circuit through a relay or an equivalent device.
An ammeter is a device that indicates the presence of an electric current by measuring the flow of electric charges through a circuit.
You can start an electric circuit by closing the circuit, typically by turning a switch on. You can stop an electric circuit by opening the circuit, usually by turning a switch off or disconnecting a wire.
