LeRoi Price 116,416 views Switches in Electronic Circuits: Poles and Throws dummies The two most common types are single throw and double throw: A single throw switch is a simple on off switch that connects or disconnects two terminals. When the switch is closed, the two terminals are connected and current flows between them. When the switch is opened, the terminals are not connected, so current does not flow. Switch Basics learn.sparkfun They allow control over current flow in a circuit (without having to actually get in there and manually cut or splice the wires).
