Switches and breakers
A crucial part of any electrical system! Here's a comprehensive overview of switches and breakers:
What are switches?
A switch is an electrical device that controls the flow of electric current in a circuit. It is used to turn a circuit on or off, or to interrupt the flow of current in a circuit. Switches are typically used to control the operation of devices such as lights, appliances, and motors.
Types of switches:
- Toggle switch: A toggle switch is a type of switch that has a lever or handle that is moved to turn the circuit on or off.
- Push-button switch: A push-button switch is a type of switch that is activated by pressing a button.
- Slide switch: A slide switch is a type of switch that has a sliding lever that is moved to turn the circuit on or off.
- Rotary switch: A rotary switch is a type of switch that has a rotating knob or handle that is used to select different positions or functions.
What are breakers?
A breaker, also known as a circuit breaker, is an electrical device that is designed to interrupt the flow of electric current in a circuit when it exceeds a certain level. Breakers are used to protect electrical circuits from damage caused by overcurrent, overheating, or other faults.
Types of breakers:
- Molded case circuit breaker (MCCB): An MCCB is a type of breaker that is designed for use in industrial and commercial applications. It is typically used to protect electrical circuits from overcurrent and overheating.
- Miniature circuit breaker (MCB): An MCB is a type of breaker that is designed for use in residential and commercial applications. It is typically used to protect electrical circuits from overcurrent and overheating.
- Ground fault circuit interrupter (GFCI): A GFCI is a type of breaker that is designed to protect people from electrical shock caused by ground faults. It is typically used in bathrooms, kitchens, and other areas where water is present.
- Arc fault circuit interrupter (AFCI): An AFCI is a type of breaker that is designed to protect people from electrical shock caused by arc faults. It is typically used in residential applications.
How do switches and breakers work together?
Switches and breakers work together to control the flow of electric current in a circuit. When a switch is turned on, it allows the current to flow through the circuit. If the current exceeds a certain level, the breaker will trip and interrupt the flow of current, protecting the circuit from damage.
In summary, switches are used to control the flow of electric current in a circuit, while breakers are used to protect the circuit from damage caused by overcurrent, overheating, or other faults.
