The single button can control the lighting switch of the two power sources, analyzes the circuit principle of the lighting switch in detail and gives the widely used lighting switches, all of which use the only button switch to control the working mode of the road lighting power supply, along with the lighting power supply road. As the number increases, it is necessary to increase the lighting switch, causing inconvenience to the use. To this end, this paper introduces a single-button two-way lighting switch, which can control the number of contacts of two power sources in sequence with only a single button, which not only saves the number of switches, but also can meet the lighting requirements of special occasions.
2 circuit principle single-button dual-channel lighting switch circuit shown in Figure 1.22 AC power supply after 14 reciprocating rectification, by deduction buck, capacitor filtering, W regulator to get 9V DC voltage supply control circuit work. It is a dual master-slave flip-flop D4013, which consists of two identical D-type flip-flops A1 and 2. Each flip-flop has an independent data input terminal D, a set terminal R, and a clock input terminal P. The rising edge triggers.
To turn on the light, press the normally open button 8 and the input of the non-1 to get a low-potential pulse, and the civilian 1 output a high-level pulse. The clock terminal P1 of the D-type flip-flop A has a rising edge and a pulsed 91 output high level. 91 output low level. 1 After outputting a high level, the unidirectional inter-well tube 8 [bucks the conduction bulb to illuminate, that is, the illuminating power source is turned on. Press 88 again, then the citizen 1 outputs the 篼 level pulse, the 0-type flip-flop 1 clock terminal 0 port 1 has the rising edge pulse, so that 91 outputs the low level, 91 outputs the high level, the unidirectional crystal tube 3 [The interception of the mountain is annihilated, that is, the road lighting power supply is cut off. At the same time, the clock terminal of the flip-flop 2 (port 2 has a rising edge pulse, 92 outputs a high level, and the output is low level. After the output is high level, the unidirectional intergranular tube 5 is lowered. That is, the second lighting power source is turned on. If you press 8 segments again, the clock terminal of 1 (port 1 has a rising edge pulse, and it becomes a high level again. Since it is also high level, the non-mouth guard 3 outputs a low level, and the non-guest 2 output high level, 0 type flip-flop 1 and 0 type flip-flop 2 reset end buckle and 62 both become high level, Al, A2 are reset, Ql, Q2 are both changed to low level, 3 [cho, 3[62 are all in the cut-off state, and they are all annihilated, that is, the two-way lighting power supply is cut off. It can be seen from the jitter analysis that the two-way illumination bulbs can be turned out and sequentially illuminated by continuously pressing the normally open button 3, thereby realizing the function of only controlling the two-way illumination power by the button.
White bulb, power should not exceed 60W.
3 Application examples The switch is widely used. This article only lists the application examples of the switch in home lighting. The switch can be used to control the desk lamp and the wall lamp, so that they are more useful. This Hl selects to say that the white light bulb is used, and the H2 selects a 3W red or other color light bulb according to the need of the self. In normal Wang Zuo and learning lighting.
When the ratio is lighted, the annihilation not only serves as a decorative light, but also provides a nighttime micro-lighting illuminator to facilitate people's nighttime life. It is especially suitable for households using infants and children, so the table lamp wall lamp becomes A dual-function luminaire that provides normal care and provides low-light decorative lighting.
The work permit for the issuance of low-voltage electrical products has begun to be based on the “Trial Regulations for the Production License of Industrial Products†and the “Administrative Measures for the License of Industrial Productsâ€. The production of low-grade electrical products formulated by the National Industrial Product Production License Office can be exchanged. The regulations are being implemented.
The implementation rules stipulate the necessary conditions for the management institutions and enterprises to obtain the piezoelectric production license, the application for the license renewal certificate and the approval procedures, and the supervision and charging methods for the production license. It also stipulates the number of cigarettes and the number of samples to be inspected. The inspection equipment and production licenses required by the production enterprises are determined by the production conditions. The low-voltage electrical appliances are divided into AC contactors and universal circuit breakers.

Automotive Push Button Switches
Automotive Push Button Switches , also called Push Button Starter Switch, is one kind of switches to turn on the car. As for the Automotive Switches , we have Automotive Push Button Switches, Automotive Toggle Switches, Automotive Rocker Switches , Automotive Rotary Switches and Automotive Battery Switches for our customers to choose.
The Starter button switches mainly based on the car button switch. The main function is to start the car, switch on the car power supply or start the car internal equipment. The automotive starter switch is mainly based on DC current and voltage, and has a wide range of dimensions. The installation size ranges from 8.5mm to 22mm directly.
Our push button switches can be matched with the dust proof and waterproof cap. When the car equipment is working in a harsh environment, our Yeswitch car start button switch could still be regularly used.
Our variety of Automotive Momentary Push Button Switch, can match different colors and different appearances of dust-proof and waterproof caps, dust-proof and waterproof grade can reach IP67 grade. Along with excellent electrical life times, high load current and voltage, our Yeswitch start button switch is not limited to automotive field , heavy machinery, and ships are also widely recognized by customers.
