One-key start-stop switch suitable for condensation water system

The utility model discloses a one-key start-stop switch suitable for a condensation water system, which comprises an upper-layer start-stop assembly and a lower-layer start-stop assembly which are arranged according to an up-and-down hierarchical relationship, the upper-layer start-stop assembly comprises a plurality of first sensors used for detecting the state of upper-layer equipment, at least one first logic arithmetic unit, a start-stop switch and a plurality of first time delay switches, and the start-stop switch is connected to a power interface of the upper-layer equipment through the first time delay switches; and the plurality of first sensors are connected to the first logic arithmetic unit. According to the device, the devices can be started and stopped in sequence, the state of each device is detected through the first sensor and the second sensor, and when one-key starting and stopping cannot be completed, which device breaks down can be visually judged through the sensors, so that maintenance i
