You need a proper key switch on the bench, in the panel, or on the machine. Not a toggle someone can flick by accident. Not a button that gets mashed. A real key in a real barrel, and only your people have the code. The Jaycar Barrel Key Switch (Key Type A) is the standard-format option — the one you reach for when the spec says 'barrel lock, Type A.' Two keys are in the box. One for you, one for whoever else needs access. Wire it up, label it, and stop worrying about unauthorised access to that circuit
