The invention relates to a safety switching device for connecting and reliably disconnecting an electrical load in response to a switching event from a safety transmitter. The safety switching device has at least a switching element and an operating mode selector unit for selecting an operating mode in response to a defined input signal. An input port is provided, which is connected to the operating mode selector unit such that the defined input signal can be supplied to the latter. The operating mode selector unit is designed such that it identifies the defined input signal as one from a group of different defined input signals. Responsive thereto, it selects an operating mode.
