False. A device that is used to open the circuit when the current flow is too great is a circuit breaker or fuse.
A disconnect switch is a manual device that isolates or turns off the load.

A switch is a device that stops and starts current flow in a circuit?
Yes, a switch is a device that stops and starts current flow in a circuit.
How does a switch control an electric device?
A switch basically represents a gap in the electric circuit. Electric current can pass through a circuit only if it is complete. An incomplete circuit can never pass a current through it. When the switch is in the 'off' position, the circuit has a break (gap) in it. When you put the switch in 'on' position, the circuit wire join and the circuit gets completed.
What is the function of switch gear?
Switchgears control electricity. They consist of switches, fuses, and circuit breakers which can be used to disconnect machines from electrical currents. This may be necessary if one wishes to fix a device without risking electrocution.
What is the difference between disconnect switch and circuit breaker?
A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow.The term switchgear, used in association with the electric power system, or grid, refers to the combination of electrical disconnects, fuses and/or circuit breakers used to isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.
What is the simple device that opens and closes an electrical unit called?
A device that opens and closes a circuit is called a switch.
A switch is a device that stops and starts current flow in a circuit?
Yes, a switch is a device that stops and starts current flow in a circuit.
How do you de energize an electrical circit?
De energising means you are disconnecting a device from electricty source. Switch off the device, physically disconnect the device to de energise the circuit.
What is the device to break a circuit?
Switch (mechanical or electrical), breaker or fuse.a switch
What device used to stop and start the flow of electricity in a circuit is a?
A switch is a device that stops and starts current flow in a circuit.
Will a circuit work without a switch?
Yes a circuit will work without a switch but the only problem will be is that electricity will be wasted and there will be no device to stop the flow of current
Will a circuit work with the switch and will it work if you take the switch out of the circuit?
A switch is used to connect or disconnect a load from a source of voltage. If you take the input and connect directly to the output the result is that the connected device is always on.
What function in a circuit for a switch?
A switch is a make - break device. Its function is a circuit is to make and break the current flow of the circuit that it is in. This action then starts and stops the load that is connected in the circuit.

What is the function of switch gear?
Switchgears control electricity. They consist of switches, fuses, and circuit breakers which can be used to disconnect machines from electrical currents. This may be necessary if one wishes to fix a device without risking electrocution.
Is a reusable safety switch that breaks the circuit when the current gets too high?
In the electrical trade, this device is known as a circuit breaker.
How can you start and stop electric circuit?
Using a switch device which starts and stops the electric current around the circuit
What happens when you open a switch in a circuit?
The current to the load stops flowing and the load device stops operating.
