Description

A new type of touch screen switch

technical field

The utility model designs a switch, in particular to a novel touch screen switch.

Background technique

Most of the existing wall switches are push-buttons, which generate electric sparks when they are switched on and off, and need to be pulled, so that there is a certain risk when using the switch. Touch screen control mode, double brightness indicator light, the switch position can be known after the light is turned off at night. Automatic recognition function, power off and then power off automatically turn off the lights, to avoid wasting power. However, most of the touch-screen wall switches on the market have complicated circuit structures, and the cost is relatively high, so it is difficult to replace the push-button switches.

Utility model content

The purpose of this utility model is to provide a new type of touch-screen switch, which can completely replace the push-button switch. It is easy to use, and the controlled electric light can be turned on or off only by lightly touching the touch screen.

In order to achieve the above object, the solution adopted by the utility model is: a novel touch screen switch, which includes a housing, a touch screen (4) and a touch circuit (3), in the touch circuit (3) the 1 junction of the rectifier N Connect the C pin of the switch tube S, the J pin of the regulator tube VD ₅ , the H pin of the capacitor C ₁ , the 4 pin of the chip QA, the B pin of the resistor R ₂ , and the 2 nodes of the rectifier N The phase line end of the mains, the 3 nodes of the rectifier N are connected to the E pin of the switch tube S, the K pin of the regulator tube VD ₅ , the I pin of the capacitor C ₁ , the L pin of the resistor R ₃ , and the rectifier N The 4 nodes of the chip are connected to the lamp Q, the 1 pin of the chip QA is connected to the F pin of the resistor R ₁ , the D pin of the resistor R ₂ , the O pin of the resistor R ₃ , and the P pin of the resistor R ₁ is connected to the touch panel M .

When the switch is working normally, pin 3 of the chip QA is at a low level, the switch tube S is not conducting, the circuit is in an off state, no current passes through the lamp Q, and the lamp Q does not emit light;

When the switch works normally and a touch signal is transmitted to pin 1 of chip QA, pin 3 of chip QA sends out a continuous high level, the switch tube S is turned on, and the mains power is delivered to the lamp through VD ₁ and VD ₃ Q, the lamp Q emits light;

After a sudden power failure in the mains power supply, the 3-pin of the chip QA automatically resets and outputs a low level, the switch tube S is not turned on, and the lamp Q does not emit light.

The utility model can completely replace the existing button-type wall switch, and is easy to use, and the controlled electric light can be turned on or off only by lightly touching the touch screen; waste.
