Problems solved by technology
[0002] Most of the time-delay switches in the prior art use the method of resistive voltage division to supply power to the control circuit. The technical limitation is that it can only delay the time for incandescent lamps. After the energy-saving lamps are connected, they will flicker continuously and cannot be used normally.

Embodiment Construction
[0012] see figure 1 and image 3 , the delay switch includes a switch panel 1, a switch housing 2, the switch panel 1 is mounted on the front opening of the switch housing 2 through buckles, there is a pressing plate 3, an indicator light 5 and A battery slot4. An electronic control board is installed inside the switch housing to realize the delayed closing of the energy-saving lamp. The battery slot 4 is connected with the electronic control board through contacts to supply power for the control circuit.
[0013] see figure 2 , when the switch S1 is pressed, the main lighting circuit is connected, and the energy-saving lamp is lit. At the same time, the S2 normally closed contact in the delay circuit is connected, and the capacitor is charged by a 4.5v DC power supply. When the capacitor is fully charged instantaneously, it is equivalent to an open circuit for the DC circuit, and the battery power consumption is zero. Both S1 and S2 are controlled by the switch board. W...

A time delay switch of an energy saving lamp comprises a switch panel, a switch shell, a time delay control circuit board, a press board, an indicator lamp and a battery holder, wherein the press board, the indicator lamp and the battery holder are installed on the switch panel. The time delay switch is characterized in that the switch panel is installed at a front opening of the switch shell, the switch shell is fixed in a wall through screws, the time delay control circuit board is installed in the switch shell, a switch line which is serially connected with a lamp is arranged on the circuit board, the indicator lamp on the switch panel is connected with the control circuit through an electronic circuit, and the battery holder is connected with the time delay control circuit board through contacts. The time delay switch is simple in structure, universal, interchangeable, low in cost, and convenient to popularize and apply; by means of the time delay switch, time delay turnoff of the energy saving lamp can be achieved, trouble brought by darkness generated by sudden light turnoff to a user who turns off a lamp to leave can be avoided, the defect of flicker of the energy saving lamp which is turned off is overcome, and the time delay switch is suitable for serving as a power switch of the energy saving lamp in houses and public places.
Description
technical field [0001] The invention relates to a time-delay switch of an energy-saving lamp, which belongs to the technical field of lighting control. Background technique [0002] Most of the time-delay switches in the prior art adopt the method of resistive voltage division to supply power to the control circuit. The technical limitation is that it can only delay the time for incandescent lamps. With the advent of the energy-saving era, incandescent lamps will eventually withdraw from the market, and delay switches that can delay energy-saving lamps are the future trend. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and propose a time-delayed lighting switch capable of loading energy-saving lamps. [0004] Technical scheme of the present invention is as follows: [0005] The invention comprises a switch panel, a switch casing, a time delay control circuit board, a pressing plate, an indicator light...
