No, it opens the supply voltage and hence the supply current to the load.

What is the device to break a circuit?

A switch is a device used to break a circuit. By opening the switch, the circuit is interrupted and electricity stops flowing. This allows for controlling the flow of electricity to different components in a circuit.


What is a device used to open and close an electric circuit?

The device is called a switch.


How a switch controls the flow of electric current?

A switch controls the flow of electric current by opening and closing a circuit. When the switch is closed, it completes the circuit, allowing current to flow through. Conversely, when the switch is open, it breaks the circuit, stopping the flow of current. This on/off mechanism enables the switch to control the flow of electricity to a device or appliance.


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 device will open or close the break in a electrical circuit?

A switch.


What is a device called which is used to break an electric circuit?

Define one way switch?

A "one way switch" or better known as a single pole switch is simply a device that breaks the electrical circuit to a device. ie; A single pole light switch is used to turn off and on lights from one location.


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 happening when you turn an electric circuit off?

When you switch off an electrical circuit you tend to create a 'break' in the circuit, preventing the electric current to flow around the circuit, this can be caused by a simple switch or a break in the circuit, e.g a disconnected wire.


What does a PTB switch do?

A PTB (Push to Break) switch is a type of switch that is normally in the ON state. When the switch is pressed or activated, it will break the circuit connection and turn OFF the device it is controlling. PTB switches are commonly used as emergency stop buttons in machinery or equipment.


How does an electric switch help in an electric circuit?

A switch is a means of making (on) or breaking (off) an electrical circuit.


What device close or breaks the circuit?

There are a number of devices that break a circuit. On motor circuits an overload block opens the circuit when the motor's current goes above the motor's nameplate rating. Likewise a fuse or a breaker will open a circuit when the current goes above their rated limit. In home wiring circuits the home devices are controlled by a simple on- off switch. Electric heating circuits are controlled by thermostats that regulate the heaters by opening and closing the heater's supply voltage.
