Provided is a wall switch with a touch-on delayed-off LED small night lamp. The wall switch comprises an L end and an N end connected to a 220V power source. The wall switch also comprises a first capacitor C1, a lamp V1, a switch K1, a second capacitor C2, a bridge-type rectifier, a third capacitor C3, a voltage-regulator tube VD1, a first resistor, a first triode Q1, a second resistor R2, a third resistor R3, a second triode Q2, a fifth diode D5, a fourth capacitor C4, a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, a third triode Q3, an eighth resistor R8, a ninth resistor R9, a tenth resistor R10, a fourth triode Q4, an LED1 and an LED2. The wall switch is simple in circuit structure and good in practical application effect, overcomes the defect of single function of an existing switch, improves applicability thereof, reduces use cost and realizes the energy saving purpose.
