Abstract

The present invention relates to a safety switching device for safely switching off an electrical load such as an electrically driven machine. The safety switching device has a failsafe disconnection unit and a non-failsafe signaling unit, both of which are supplied with an external control signal. The disconnection unit fail-safely switches off the electrical load as a function of the control signal but with a first delay. The signaling unit produces an external reporting signal as a function of the control signal in a non-delayed and non-failsafe manner.
