The embodiment of the invention discloses a circuit detection method, a switch safety circuit, a device, a vehicle and a storage medium. The method is applied to a switch safety circuit, the switch safety circuit comprises a vehicle body controller and a power-off switch circuit, the vehicle body controller is connected with the power-off switch circuit in series, and the method comprises the steps that when a power-off switch is pressed down, first voltage and second voltage output by the power-off switch circuit are obtained through the vehicle body controller, the first voltage is the voltage, collected by a first switch detection interface in the vehicle body controller, of a first key switch interface in the power-off switch circuit, and the second voltage is the voltage, collected by a second switch detection interface in the vehicle body controller, of a second key switch interface in the power-off switch circuit; and performing fault detection on the power-down switch based on the first voltage and the second voltage. According to the method, fault detection can be carried out on the power-down switch based on multiple paths of acquired switching voltages, and the detection failure rate is reduced.
