How to Choose Right Rocker Switch
What Is a Rocker Switch?
A rocker switch is a mechanical switch that rocks in one direction to open a circuit and the other to close it. Unlike push buttons, these switches stay in place once toggled. They are widely used in household appliances, power equipment, automotive dashboards, and industrial control systems.
How Does a Rocker Switch Work?
A rocker switch controls the flow of electrical current by rocking between two positions. Pressing one side of the switch completes the circuit, allowing current to flow. Pressing the opposite side breaks the circuit. Rocker switches come in several configurations, including:
- SPST (Single Pole Single Throw)
- SPDT (Single Pole Double Throw)
- DPST (Double Pole Single Throw)
- DPDT (Double Pole Double Throw)
Each configuration determines how many circuits the switch controls and how many outputs are available.

Types of Rocker Switches
1. Momentary Rocker Switch
Returns to the default position after being pressed. Common in starter switches and temporary functions.
2. Latching Rocker Switch
Maintains its position after being toggled. Used in devices where power needs to remain on or off until changed manually.
3. Illuminated Rocker Switch
Equipped with built-in indicators (like LEDs) that light up when the switch is active. Ideal for visible control in dark environments.
Applications of Rocker Switches
- Extension cords and power strips
- Audio and video equipment
- Kitchen and home appliances
- Automotive electrical systems
- Industrial control panels
- Medical and laboratory equipment
- DIY electronics and robotics projects
How to Choose the Right Rocker Switch
Electrical Rating
Match the voltage and current rating (e.g., 6A 250V AC) to your circuit requirements.
Switch Type
Determine if you need SPST, SPDT, DPST, or DPDT functionality.
Mounting Type
Choose from panel mount or PCB mount based on the design.
Terminal Style
Options include solder lugs, quick-connect terminals, or screw terminals.
Illumination
If visibility is needed, select a switch with a built-in light.
Durability
Look for switches rated for long life cycles and high-temperature resistance.
