    • A safety switch for safety circuit arrangement has a control part for processing an input signal and at least one switching element with at least one active and one inactive switching state. The control part controls the switching element in order to generate an output signal dependent on the input signal at an output. In addition, the safety switch has a diagnostic function for identifying a functional fault. The control part is configured to transfer the switching element into the inactive state when a functional fault is identified. According to one aspect of the invention, the control part is also configured to generate a data message at the output, which data message is dependent on the functional fault.
    • 用于安全电路装置的安全开关具有用于处理输入信号的控制部分和具有至少一个有效和无效切换状态的至少一个开关元件。 控制部分控制开关元件,以便根据输出端的输入信号产生输出信号。 另外,安全开关具有识别功能故障的诊断功能。 控制部分被配置为当识别功能故障时将开关元件传送到非活动状态。 根据本发明的一个方面,控制部分还被配置为在输出端生成数据消息,该数据消息取决于功能故障。
