An inline rocker switch is designed to be placed in the middle of a power cord or cable. It typically consists of a small plastic or metal box that contains the switch mechanism, which is operated by a rocker or paddle.
When the switch is in the "on" position, the circuit is closed, and electricity is allowed to flow through the cord. When the switch is in the "off" position, the circuit is open, and no electricity can pass through the cord.
Inline rocker switches are commonly used in a variety of electronic devices, such as lamps, fans, and small appliances. They are popular because they provide a convenient way to turn a device on and off without having to unplug it from the wall or outlet.
