A toggle switch is an electrical control device distinguished by a mechanically operated lever that flips or “toggles” to a distinct position to either close (ON) or open (OFF) an electrical circuit. They are generally “maintained” switches, meaning they stay in the position they are set to until manually changed. Classified by their internal circuitry, such as Single-Pole, Double-Throw (SPDT) for controlling one circuit between two connections, these switches are valued for their durability, clear tactile feedback, and are extensively used in applications from industrial control panels and machinery to marine and automotive systems.
