ON-OFF

The ON-OFF concept describes how a device or system switches between two states: ON (active or functioning) and OFF (inactive or not functioning). For example, a light switch controls a light; when ON, the light is on and working, and when OFF, the light is off. This binary operation is common in electronics, machinery, and digital systems, where clear, simple control over a device’s status is essential. It helps manage energy use, control processes, and ensure safety by enabling quick, decisive switching between operational states.
