Rocker Switch is a common power control switch that looks like a boat. When using it, you only need to press one end lightly and the other end will automatically pop up, forming a "rocker" action.
The core of Rocker Switch consists of the following parts:
Rocker: the external depressible part that controls the switch action;
Spring mechanism: used to realize the feedback of rebound after pressing;
Contacts: the contact is conductive when the power is on and separated when the power is off;
Terminals: connected to the external circuit.
Rocker Switch is based on the principle of mechanical switch and controls the on and off of the circuit by operating the button up and down. The specific process is as follows:
Circuit on and off: when the user presses one end of the switch, the contacts inside the switch are closed, the circuit is connected, and the current starts to flow; when the user releases or presses the other end, the contacts are disconnected, the circuit is cut off, and the current stops flowing.
Mechanical operation: the switch button is connected to the internal contacts through a rotating shaft. The up and down swing of the operating button will drive the contacts to close or open, thereby realizing the control of the circuit.

The on-off control depends on the connection or separation of the internal metal sheet
Common types of contact configurations for Rocker Switch:
Type | Abbreviation | Description
Single-pole single-throw | SPST | One input, one output, the most basic switch
Single-pole double-throw | SPDT | One input, two outputs, switching function
Double-pole double-throw | DPDT | Two sets of switching circuits, controlling two channels
Common application scenarios for Rocker Switch:
Power switch (such as audio, rice cooker)
Car modification switch (LED light bar control)
Electric vehicle dashboard switch
Industrial equipment control console
Advantages of Rocker Switch:
Intuitive and reliable operation;
Can be equipped with light prompts (commonly red, green, and blue LEDs);
High life (up to 50,000 times);
Easy to embed in the panel for installation;
