A single pole single throw switch is used to control a lamp by connecting or disconnecting its two terminals. The switch works on the principle of making or breaking an electrical circuit. When the switch is on, it connects the two terminals allowing current to flow through the lamp, powering it. When the switch is off, it breaks the connection between the terminals, stopping the current from reaching the lamp and turning it off. The switch provides easy operation and requires fewer wires than other wiring methods. Safety warnings are provided to disconnect power before working with electrical equipment.
