The invention discloses a lamp and a power switch control circuit. The power switch control circuit comprises a 555 timer, a switch module, a switching tube, and an AC power supply. The switch module comprises a turning-on metallic sheet and a turning-off metallic sheet which are used for being touched by a user. The setting end of the 555 timer is connected with the turning-on metallic sheet while the resetting end of the 555 timer is connected with the turning-off metallic sheet. The output end of the 555 timer is connected with the control end of the switching tube. The first end of the switching tube is connected with the first end of a load. The second end of the load and the second end of the switching tube are connected with the two ends of the AC power supply, respectively. When the technical scheme of the invention is executed, the power switch control circuit achieves large current control with a small signal because a conventional mechanical switch is replaced by a touch switch. Therefore, faults caused by a fact that large current passes through the mechanical switch when the mechanical switch performs switch operation can be prevented.
