An Overview of Switches
A switch is an electronic device used to control the current flow in a circuit. A switch, essentially, can prolong the lifespan of the circuit without constantly opening all the time. At least one or more switches are commonly used to perform ON ("Open") and OFF ("OFF") operations.
The Characteristics of Switches
Different types of switches have different features and capabilities depending on their applications but certain common characteristics form a switch.
Pole and Throw – pole and throw are the common parts switch has. One indicates the number of switch controls and another indicates the contact points.
Current control – A switch can regulate the current flow between two locations in a circuit, allowing current to go through when the switch is closed (OFF) and block it when it is open (ON).
Types of Switches
Mechanical switches move the physical pole to close or open a circuit. It requires physical actions to press or touch to make the switches work. In terms of electronic switches, they use semiconductor action. Therefore, they need no physical action to regulate the flow of the current.
