Title: SWITCH-ON/OFF CIRCUIT AND DROPLET DETECTOR
Abstract:
A switch-on/off circuit (10) and a droplet detector (1) therefor. The switch-on/off circuit (10) comprises a power supply input end (101) for receiving a power supply signal, a manual control switch (102), a power supply switch (103), a switch-on control circuit (104), a first switch-off control circuit (105) and a power supply output end (107) connected to a load circuit (30). The manual control switch (102) is used for receiving an external user input operation, and the duration of the input operation is respectively a first time and a second time different therefrom. When the duration of the input operation is the first time, the switch-on control circuit (104) outputs a switch-on signal. When the duration of the input operation is the second time, the first switch-off control circuit (105) outputs a control signal to the switch-on control circuit (104), and the switch-on control circuit (104) outputs a switch-off signal according to the control signal. The power supply switch (103) receives the switch-on signal and the switch-off signal so as to correspondingly selectively control the electrical connection or disconnection between the power supply input end (101) and the power supply output end (107), such that the power supply output end provides or stops providing a power supply signal to the load circuit (30).
