The invention discloses a power supply main switch with a delayed power-off function, which comprises a control unit, a switch K, an LED indicating lamp L and an alarm, and is characterized in that the switch K is connected with the control unit, the control unit is connected with the alarm, and the power supply input end of the control unit is provided with an external power supply; the control unit comprises a signal processing decision-making device, a data transceiving device and a voltage conversion device, and the signal processing decision-making device is bidirectionally connected with the data transceiving device. According to the invention, the control unit, the switch K, the LED indicating lamp L and the alarm are integrated in one switch, so that the size of the power supply main switch is small, the time-delay power-off function of the whole vehicle can be realized only through one switch, the occupied space is small, the difficulty of arrangement and installation is reduced, and the maintenance and repair are more convenient; and a whole vehicle power supply relay fault detection function, an alarm function and a fault information reading function are added.
本发明公开了一种带延时下电功能的电源总开关,包括控制单元、开关K、LED指示灯L和报警器,开关K与控制单元相连接,控制单元与报警器相连接,控制单元的供电输入端设置有外接电源,控制单元包括信号处理决策装置、数据收发装置和电压转换装置,信号处理决策装置和数据收发装置双向连接,控制单元、开关K、LED指示灯L和报警器。本发明通过将控制单元、开关K、LED指示灯L和报警器集成在一个开关内的设置,使得电源总开关体积小,仅需一个开关即可实现整车延时下电功能,占用空间较小,减少了布置、安装的难度,对于维护、检修更加方便,并且添加整车电源继电器故障检测功能、报警功能及故障信息读取功能。
