A switch operated using a key is called a key switch. These are often used in areas that are highly secure or require limited access. A key switch allows a particular switch or control to only be accessed by authorised key holders. Depending on the level of security needed, the key can be either a traditional metal key or a more complex barrel key.
A key switch operates by connecting a circuit and sending a current of electricity when the key is turned. They may be used in a variety of applications including; doors, gates, roller shutters, equipment or machinery in industrial settings, public corridors and lighting systems.
