A rocker switch is an electrical switch, often used to turn devices on or off, that is operated by a rocking motion, similar to a seesaw. The switch consists of a rectangular or square-shaped body with a hinged actuator that pivots around a central axis. When one side of the actuator is pressed, it makes contact with one set of terminals, and when the other side is pressed, it makes contact with a different set of terminals. This rocking action allows the user to easily control the flow of electricity to a circuit or device.
The switch consists of a rectangular, round or square-shaped body with a hinged actuator that pivots around a central axis.

This rocking action allows the user to easily control the flow of electricity to a circuit or device.
Key features of rocker switches:
Actuator: The “rocker” itself is a lever that pivots.
Switch Body: A rectangular or square-shaped housing that holds the rocker and electrical contacts.
Contacts: Metal contacts within the switch that make or break the electrical connection when the rocker is moved.
Mounting: Designed for various mounting methods, including panel mounting, PCB mounting, or direct soldering.
Wiring: Requires connecting the switch terminals to the appropriate wires in the circuit.
Function: Primarily used to switch electrical circuits on and off.
Terminology:
Normally Open (NO):
A push button where the circuit is broken when the button is not pressed and closed (circuit connected) when pressed.
Normally Closed (NC):
A push button where the circuit is closed (circuit connected) when the button is not pressed and broken (circuit open) when pressed.
SPST: Single Pole Single Throw
SPDT: Single Pole Double Throw
DPST: Double Pole Single Throw
DPDT: Double Pole Double Throw
PTM/RTB: Push To Make/Release To Break
These terms refer to the number of poles and throws in the switch, describing the electrical circuitry.
