Abstract

The utility model discloses a two-wire controlled light contact multi-control switch which comprises switch boards, a load relay, and a switch way circuit, wherein the switch way circuit comprises a switch board circuit, a control circuit and a power supply circuit. Control wires connected between the switch board circuit and the control circuit are two wires; the control circuit is provided with a relay and an electrolytic condenser. More than two switch boards are used, wherein one of the switch boards is provided with a color-changing light emitting diode, and each of the rest switch boards is provided with a light emitting diode. The utility model displays the switching on/off state by light emitting with multiple control, and uses weak current to control with the function of time delay. Thus, the utility model is applied to the switches of electric appliances which need time delay protecting function and ordinary electric appliances.

Description

Two-wire control soft-touch type more-control switch

The utility model relates to a kind of derailing switch, especially a kind of soft-touch type control switch.

The soft-touch type of two-wire control at present more-control switch adopts integrated circuit more, though have multiple spot control, but switchboard does not have attaching light-emitting diode or variable color light-emitting diode, thereby position that can not the indicator cock plate, in the dark can not be from the residing open and close state of perception control circuit on the switchboard.On the other hand, because it is quite high that ic manufacturing process requires, the quality testing difficulty of integrated package, and the control circuit that adopts integrated circuit control is in the normal course of work, level to the circuit each point is strict, control procedure also is subject to the influence of external environment (as temperature, humidity, power supply etc.), thereby its quality of more-control switch finished product that adopts integrated circuit to make at present also is difficult to guarantee.

The purpose of this utility model is to provide the reliability high soft-touch type multipoint control switch of a kind of two-wire control with luminous indication open and close state and relevant time-lag action.

The utility model comprises switchboard, load-relay and switch way circuit.The switch way circuit comprises switchboard circuit, control circuit and power circuit, between switchboard circuit and the control circuit control line is arranged, and control line adopts two leads, and control circuit has a relay and 1 electrochemical capacitor.Be connected to the switchboard more than 2 on the control line, wherein 1 switchboard has 1 variable color light-emitting diode, and the rest switch plate all has 1 light-emitting diode, and every switchboard all has transparent frame.

Fig. 1 is the utility model embodiment system schematic;

Fig. 2 is the switch way circuit figure of embodiment.

See figures.1.and.2, the utility model comprises switchboard 1, load-relay J ₂With the switch way circuit, the switch way circuit comprises switchboard circuit 5, control circuit 4 and power circuit 6; Be connected with control line 2 between switchboard circuit 5 and the control circuit 4.Control line 2 has only the double joint lead, and control circuit 4 has 1 relay J 1 and 1 electrochemical capacitor C1.4 switchboards 1 are connected on the

control line

2, and 4 switchboards 1 all have transparent frame 3, and wherein 1 switchboard 1 has 1 variable color light-emitting diode D ₁, all the other 3 switchboards respectively have 1 light-emitting diode D.Civil power outage back incoming call, relay J ₁The contact is in release condition all the time, and circuit is controlled to be " pass " state, load-relay J ₂Coil losing electricity, load power source is turned off.When power supply passes through R ₅To C ₁After charging is finished, BG ₁, BG ₃The base stage no current, BG ₁, BG ₃Be in off state; BG ₂Base stage has electric current, is in conducting state, and electric current just flows through a variable color light-emitting diode D1 and three light-emitting diode D from the UA branch, and J again confluxed ₁Coil is to U ₈, D like this ₁All luminous with D.When touching arbitrary button 7, pass through J ₁The electric current of coil obviously increases, J ₁The contact adhesive.Behind release-push 7, relay J ₁Be in self-locking state, BG ₄Conducting, J ₂Coil gets electric, and load power source is switched on.J ₁C when being in self-locking state ₁Discharge, BG simultaneously ₁, BG ₃Conducting, BG ₂Turn-off, at this moment electric current is arranged from U _AFlow through J ₁Contact, D ₁₅, D ₁Again through BG ₃To U _m, D like this ₁Variable color is luminous, and D is not luminous.When touching arbitrary button 7 once more, from U _AFlow through J ₁The electric current of the contact D that mainly flows through ₁₅, BG ₃To U _B, make to make J through the obvious minimizing of the electric current of J1 coil ₁The contact discharges.J ₁After the contact discharges, electric current is arranged from U _AFlow through BG ₁Base stage through R ₅To C ₁Charging, C ₁The process BG of charging ₂Disconnected, BG ₃Logical, all almost there is not electric current through J even touch arbitrary button in this process ₁Coil, J ₁The contact can not be closed, and circuit is in and closes the time-delay stage, that is to say, touches arbitrary button 7 in the pass time-delay stage, and control circuit all can not change " opening " state over to, according to the needs of many control electrical equipment, changes big C like this ₁Capacity just can increase the time of closing time-delay.

The utility model adopts the control of soft-touch type multiple spot, and switchboard has the diode displaying on off state, and easy to operate, indication is clearly demarcated.This switch adopts the control of safe voltage weak current, and joins the good switchboard of water resistance, handling safety.Use this switch must just connect through the controlled appliances power source in artificial affirmation back after civil power is sent to, circuit control also has delay function, is particularly suitable for the electrical equipment facility of time-delay start after the needs outage is shielded.The switchboard that is mixed with is ultra-thin light and handy, and Pasting is fixed in multiple body of wall during installation, also adopts the path lead-in wire simultaneously, and installation cost is low and quick reliable.This ON-OFF control circuit is simple, functional reliability is high, cost is low, and alternative regular tap uses.
