Startup circuit

The utility model provides a starting-up circuit. The starting-up circuit comprises a signal triggering module used for generating a triggering signal and a switch control member. Wherein the switch control part is used for converting the trigger signal into a power-on control signal which controls a power switch button to be powered on and changes periodically, and the input end of the signal trigger module is electrically connected with the input signal end; the input end of the switch control part is electrically connected with the output end of the signal triggering module, and the outputend of the switch control part is electrically connected with a power switch button. According to the utility model, only one switch control member is electrically connected with the signal trigger module, so that the power switch button can be controlled to carry out automatic startup, the time delay is reduced, the structure is simple, and the manufacturing cost of the startup circuit is reduced. 本实用新型提供一种开机电路，包括：用于产生触发
