Abstract

The utility model belongs to the field of switch control of a lighting lamp, and particularly relates to a touching electronic switch which can control an electrical appliance at a plurality of positions. The utility model comprises a constant voltage power supply, a touching switch, a control circuit and a drive circuit, and is characterized in that the touching switch is connected with the control circuit; the control circuit is connected with the drive circuit; more than three touching electric poles which are connected together are arranged on the inner part of the touching switch. Because more than two touching electric poles are arranged on the inner part of the touching switch of the utility model, each touching electric pole is connected by an electric line; the application is controlled through the touching electric poles. The utility model has the advantages of reasonable design, convenient installation, and electric line saving, and is a control switch which can control the electrical appliance at a plurality of positions.

Description

Touching electronic switch

Technical field

The utility model belongs to luminous lamp switch control field, especially relates to a kind of touching electronic switch that can control an electrical appliance at multiposition.

Background technology

In the prior art, be installed in the illuminating lamp of occasions such as parlor, meeting room, corridor, often wish in use and can control in many places, but commercially available power control switch is difficult to be implemented in the effect of an illuminating lamp of many places control at present, and when controlling with ganged switch, the connection of circuit relatively difficulty, wiring is complicated, and waste is big, therefore, a kind of many places of realizing of development are controlled the switch of same electrical appliance and are accorded with the demands of the market.

Summary of the invention

The purpose of this utility model is for a kind of simple in structure, easy to install, the touching electronic switch that can control an electrical appliance at multiposition is provided.To achieve these goals, the utility model has adopted following technical solution: it comprises stabilized voltage power supply, soft-touch control, control circuit and drive circuit, it is characterized in that described soft-touch control and control circuit join, control circuit and drive circuit join, and are provided with at least two continuous touch electrode points in the described soft-touch control.

Because the soft-touch control of utility model is made up of two above touch electrode points, thereby can only each touch electrode point be linked to each other with a wire, and control electrical appliance by the touch electrode point, it has advantage reasonable in design, easy for installation, that save electric wire, is the control switch that same electrical appliance is controlled in the realization many places.

Embodiment

With reference to accompanying drawing: the new small-sized D.C. regulated power supply 1 that comprises of this practicality, soft-touch control 2, control circuit 3, drive circuit 4, described soft-touch control 2 joins with control circuit 3, control circuit 3 joins with drive circuit 4, is provided with a plurality of touch electrode point M1, M2, M3,------Mn in the described soft-touch control 2.Described D.C. regulated power supply 1 is formed by connecting in known manner by capacitor C 1, C2, diode D1, D2 and resistance R 1, capacitor C 1 plays the step-down effect, diode D1 is a voltage stabilizing element, and diode D2 plays rectified action, and resistance R 0 is the bleeder resistance of stored voltage on the capacitor C 1; Touch switch circuit 2 is by a plurality of interconnected touch electrode point M1, M2, M3,------Mn, resistance R 1 and R2 formation; Resistance R 1 one ends are connected with a plurality of touch points, and the pin 3 of an end and integrated circuit (IC) 1 and the end of R2 join, the other end ground connection of R2; Described control circuit 3 by integrated circuit (IC) 1, resistance R 3, R4, R5 and capacitor C 3, C4, constitute, integrated circuit (IC) 1 is a double D trigger, its pin 1-6 is one of them d type flip flop, pin 8-13 is another d type flip flop, pin 1 joins with pin 11, be serially connected with resistance R 3 between pin 1 and the pin 4, be connected to C4 between pin 4 and the ground, pin 5 be connected with pin 14 power positive end (+12V), pin 6,7,8 continuous ground connection, pin 9 joins with pin 12, and pin 2 is unsettled, pin 10 connect respectively C4 to+12V and R5 to ground, constitute automatic reset circuit; Pin 13 joins through resistance R 4 and drive circuit 4; Drive circuit 4 is made of bidirectional triode thyristor T, and its control end is connected with the pin 13 of IC1 through resistance R 4.

When the utility model uses, the concrete operation principle of circuit is: 220V voltage provides working power through C1 step-down D1 voltage stabilizing D2 rectification C2 filtering acquisition+12V direct voltage to subsequent conditioning circuit, d type flip flop (1-6 pin) IC1-a in the integrated circuit (IC) 1 constitutes monostable trigger-action circuit, when staff touches M1-Mn, 3 pin of IC1 just have the high level of a positive transition, thereby make the pin 1 output high level of IC1, this high level charges to C3 through resistance R 3, when voltage reaches reset level on the pin 4 of IC1, the pin 1 of IC1 automatically restores to low level, and this process is gone round and begun again.Be M1-Mn of every touch, IC1 pin 1 all can be exported a high level return-to-zero automatically then.Another d type flip flop (8-13 pin) IC1-b is a flip-flop circuit, when the high level of a positive transition of input pin 11 inputs, will make the flip-flop circuit upset once, make output pin 13 transfer high level to by low level, or be low level by high level upset, extremely link to each other by the control of resistance R 4, when pin 13 output high level with bidirectional triode thyristor T, bidirectional triode thyristor T conducting, making load get electric work is that lamp is bright; Otherwise bidirectional triode thyristor T ends, and load outage lamp is put out.

Claims
