Low voltage switching are gadgets or switches that function by preventing as well as reducing the extent of high voltages or surges. They also keep electrical parameters in check as well as help maintaining a favorable electric current which cannot destroy or damage an electric product.
These types of switches play a very important role in electricity as well as electrical products by preventing or minimizing damage to the products as well as controlling the required time and period a particular electric current should be running. The absence of these switches would basically mean doom to companies and machines which require electricity to run them.
Some switches are electrically, manually or automatically operated/powered. Some use electromagnetic power while others use electrical power to either switch on or off an electric current. Manually controlled switches include power switches, relays, surge protection devices and the button switches. Automatically controlled switches include power contactors and some types of relays such as PCB power relays.
Relays are types of switches that are electrically powered and use an electromagnet and a switch to control the amount of electricity needed by a particular product. Relays are highly diverse since they can be controlled manually and automatically and can also be used to control and handle both low power and high power products. High power is usually used to control a contactor or an electric motor. Examples of relays include power relays, digital relays, monitoring relays and electromechanical relays.
Huge companies highly depend on these types of switches while putting into consideration the fact that a small electric surge can destroy an entire machine. In situations where the electric current has to be kept in check, electric circuit breakers come in handy. These types of low voltage switches also play a very important role in breaking circuits especially when surges occur. An example is the circuit breakers.
Unlike relays, circuit breakers are automatically operated which makes them user friendly. A good thing about these circuit breakers is the fact that they can be switched on or off manually or automatically. They’re primarily designed to protect an electric circuit from any form of damage which may be caused by an overload or a short circuit. They also function by detecting a fault as well as interrupting a current flow of electricity. An advantage about circuit breakers is the fact that depending on the appliance or machine used different circuit breakers are readily available for selection. An example is the switch gear which is designed to protect high voltage circuits especially those feeding huge cities.
Due to their wide range of functions, low voltage switches are grouped depending on their functions as well as their power ability. Some are used to protect high power voltages while others are used to mediate low power voltages. Example of a low power voltage resistor is the fuse. These are types of switches that function as sacrificial lambs in electric pathways during electrical surges or short circuits. Fuses also function as circuit breakers.
Regardless of the application, low voltage switches play a very important role in any industry hence their continuous use in the industry.Read less
