摘要： A power supply and a switch apparatus are disclosed. The power supply is designed for providing a liquid crystal display with a power source. In the present invention, a bouncing switch is used for power-on and power-off functions. When the bouncing switch is activated, the power to the main system is also activated and the supply of power to the main system is maintained. A controller of the main system is then activated to acquire an authorization for controlling the power to the main system so that power is continuously supplied to the main system. Then, the main system sequentially activates the power supply of each sub-system. If the bouncing switch is activated by a second triggering, the main system may sequentially turns off the power module inside each sub-system. Finally, the power to the main system is shut down to lower the static power consumption of the whole system.
