This class-2 safety switch has a switching element that's not physically connected to the actuator but is functionally brought together or separated when switching. When the safety device is opened, the actuator is separated from the base device. During this process, the NC (normally closed) contacts in the safety switch are positively opened and the NO (normally open) contacts are closed.
