Generally a circuit breaker (like a light switch)
But I guess you could use a resistor of the right resistance
If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit
The definition of a switch is a device that closes and opens an electrical circuit.
If someone only connect one of the wires to the bulb holder, the circuit will be open and the lamp will not light. This is the same principal that a switch in the circuit does. It opens and closes the circuit.
The knee joint is an example of a body joint that opens and closes as it flexes and extends during movement.
A switch in a circuit controls the flow of electricity by opening or closing the circuit. When the switch is closed, it allows electricity to flow through the circuit, and when it is open, it stops the flow of electricity. Switches are commonly used to turn devices on and off.
When you turn on a light switch in a room, it closes the circuit. This allows electricity to flow through the wiring to the light fixture, illuminating the bulb. Conversely, turning off the switch opens the circuit, stopping the flow of electricity and turning off the light.

The definition of a switch is a device that closes and opens an electrical circuit.
An electrical device activated by a current that opens or closes another circuit is called a relay. A contactor also falls into this category.
A relay is a switch which opens / or closes a circuit
A relay is an electronic switching device that opens or closes a circuit. An electromechanical relay would be one that is opereated remotely using an electrical circuit that mechanically operated the relay, which in turn opens/closes the second ciruit.
