Computer Hardware Terms, Glossary and Dictionary

Toggle means to switch from one setting to another. A toggle switch is a generic class of electric switch that uses a mechanical lever, handle or rocking mechanism to actuate it. A toggle switch has just two positions. For example, light switches that turn a light on or off are toggle switches. On computer keyboards, the Caps Lock key is a toggle switch because pressing it can have two meanings depending on what the current setting is. If Caps Lock is already on, then pressing the Caps Lock key turns it off.
