The invention provides a switch interface circuit. The switch interface circuit is used for monitoring and controlling a first switch, a control end of a second switch of the switch interface circuit is connected with a signal input end, a first connecting end of the second switch is connected with a power supply, and a second connecting end is grounded; the control end of the first switch is connected with the first connecting end of the second switch, the first connecting end of the first switch is connected with a power supply, and the second connecting end is connected with the first signal output end; when the second switch is closed, the first switch is closed. Therefore, the input signal of the signal input end can control the first switch by controlling the second switch, and the output signal of the first signal output end can represent the on-off state of the first switch, so as to monitor the first switch. The invention further provides an automobile comprising the switch interface circuit.

    本发明提供一种开关接口电路。该开关接口电路用于监控及控制第一开关,该开关接口电路的第二开关的控制端与信号输入端连接,第二开关的第一连接端连接电源且第二连接端接地;第一开关的控制端与第二开关的第一连接端连接,第一开关的第一连接端连接电源且第二连接端与第一信号输出端连接;其中,第二开关闭合时,第一开关闭合。如此,信号输入端的输入信号能够通过控制第二开关来控制第一开关,且第一信号输出端的输出信号能够表征第一开关的通断状态,以实现对第一开关的监控。本发明还提供包括上述开关接口电路的汽车。
