Rocker switches are electric switches featuring a rocking mechanism that toggles between on/off states. They are widely used in industrial, automotive, and consumer electronics for their durability and clear tactile feedback. Modern advancements have enhanced their load capacity, environmental resistance, and integration capabilities with smart systems.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Single-Pole Single-Throw (SPST) | Simple on/off control with one circuit path | Lighting systems, small appliances |
| Single-Pole Double-Throw (SPDT) | Switches between two circuits with one input | Motor direction control, HVAC systems |
| Double-Pole Single-Throw (DPST) | Simultaneously controls two circuits | Industrial machinery power isolation |
| Double-Pole Double-Throw (DPDT) | Switches two inputs between two outputs | 3D printer heater control, robotics |
| Illuminated Rocker | Integrated LED indicators for status visibility | Aircraft panels, medical equipment |
Typical construction includes: - Actuator: Rocker arm with ergonomic design (PC/ABS material) - Contact System: Silver alloy contacts with anti-oxidation coating - Housing: Flame-retardant thermoplastic (UL94 V-0 rated) - Mounting Hardware: Threaded bushing with 12mm/16mm standard sizes - Terminal Types: Quick-connect terminals (Faston) or PCB pins
