What Does Kill Switch Mean?
A kill switch is a form of safety mechanism used to completely shut off a device in case of an emergency situation where it cannot be shut off using the normal process or if immediate shut off is required. This has traditionally been used in factories and industrial facilities to shut off the system in case of emergency. To make the switch visible to everyone, it often appears as a “big red button.”
Techopedia Explains Kill Switch
A kill switch, as the name implies, is a switch that can kill or disable something, be it be a production line, a complicated nuclear power system or a consumer device like a cell phone or tablet. Its function is as a safety mechanism or an emergency stop to whatever process is happening. Physical safety is its function in industrial environments such as factories where large machinery operates and can potentially malfunction, and it is especially useful if a worker is in danger.
