Toggle switches are manually operated electrical components used to open or close circuits by mechanical movement. They serve as fundamental interface elements in electronic systems, enabling users to control power flow or signal transmission. These switches remain critical in modern technology due to their reliability, simplicity, and cost-effectiveness across industrial, commercial, and consumer applications.
| Type | Functional Features | Application Examples |
|---|---|---|
| Lever Toggle Switch | Single or multi-position operation with lever actuator | Power control in audio equipment |
| Slide Toggle Switch | Linear sliding motion for circuit control | Mode selection in portable electronics |
