Red Colour Waterproof Latching Rocker Toggle Switch is a type of switch that rocks back and forth , an action where one end is raised and the other is depressed, much like how a seesaw works when pressed, instead of tripping or staying depressed. One side of the switch is on and the other is off; these are usually marked with a "1" for on and "0" for off. https://youtu.be/R8tWxQNNr8w?si=Kh0qNqvZa72LHDNq Specification: Waterproof Latching Rocker Toggle Switch,4 pins Red AC250V/16A Certification: CCC,CE,CQC,RoHS Switch Type : Rocker Switch Model Number : KCD4 Features: Latching Material : Plastic Current: 20A Item Type : Switches Voltage: AC250V/16A AC125V/20A Color: RED Waterproof Toggle Switch Packages Include: 1 x Waterproof Latching Rocker Toggle Switch
