Technical Field

The utility model relates to a switch especially relates to a stair switch based on single line is connected.

Background

At present, the stair switch (two switches are used for controlling one lamp) is greatly convenient for production and life of people and has an important electricity-saving function, but the conventional stair switch usually uses a conventional single-pole double-throw switch and has the technical defects that ① two switches are connected by two leads, so that the use cost of the leads is high, ② the conventional stair switch cannot be effectively used when two connecting leads are short-circuited or one of the two connecting leads is broken, and ③ the conventional single-pole double-throw switch has three binding posts and needs to have certain professional knowledge or experience in installation.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a stair switch based on single line connection that simple structure, be convenient for install and use, especially can show reduction wire use cost is provided.

In order to solve the problem, a stair switch based on single line connection, its characterized in that: the switch comprises a wiring terminal A, a wiring terminal B, a fixed contact C, a fixed contact D, a rectifier diode E, a rectifier diode F and a movable contact, wherein the wiring terminal A is communicated with the movable contact, the fixed contact C and the fixed contact D are respectively communicated with the wiring terminal B through the rectifier diode E and the rectifier diode F, and the polarities of the rectifier diode E are opposite when the rectifier diode E is connected between the fixed contact C and the wiring terminal B and the polarity of the rectifier diode F is connected between the fixed contact D and the wiring terminal B.

The specifications of the rectifier diode E and the rectifier diode F are the same.

And the wiring terminal A, the wiring terminal B, the fixed contact C, the fixed contact D and the movable contact are fixed on the same base.

Compared with the prior art, the utility model has the following advantage:

1. because the utility model discloses in only be equipped with terminal A and terminal B, consequently, more traditional single-pole double-throw switch has professional knowledge skill or experience requirement when three terminal can effectively reduce the installation, is convenient for install and use.

2. Because the utility model discloses in be equipped with rectifier diode E and rectifier diode F, consequently, can utilize rectifier diode's one-way electric conductivity, two can effectively realize the break-make of electric current when the stair switch connects.

3. Connection between the stair switch only needs a wire, consequently, can show reduction wire use cost.

4. Connection between stair switch only needs a wire, consequently, when short circuit or one of them break the trouble appear in two connecting wire between traditional stair switch (traditional single-pole double-throw switch), can use the utility model discloses replace traditional stair switch (traditional single-pole double-throw switch) to continue to realize with a lamp of two on-off control.

5. The utility model discloses the selection and the order of terminal do not influence its effect when using.

Detailed Description

As shown in fig. 1, the stair switch based on single wire connection comprises a terminal a1, a terminal B2, a fixed contact C3, a fixed contact D4, a rectifier diode E5, a rectifier diode F6 and a movable contact 7, wherein the terminal a1 is communicated with the movable contact 7, the fixed contact C3 and the fixed contact D4 are communicated with the terminal B2 through the rectifier diode E5 and the rectifier diode F6 respectively, and the polarity of the rectifier diode E5 is opposite when the rectifier diode E6 is connected between the fixed contact C3 and the terminal B2 and the polarity of the rectifier diode F6 is connected between the fixed contact D4 and the terminal B2.

The rectifier diode E5 and the rectifier diode F6 have the same specification.

The terminal A1, the terminal B2, the fixed contact C3, the fixed contact D4 and the movable contact 7 are fixed on the same base.

As shown in FIG. 2, for a stair switch based on single line connection use wiring and principle to show, obviously only need a connecting wire between two switches, only need during the use with its connect after reconnection between live wire and lamp (with electrical apparatus), and the selection order of terminal does not influence its effect.

As shown in fig. 3, for the use and principle of the conventional stair switch, it is obvious that two connecting wires are needed between the two switches, and when the stair switch is used, the two connecting wires need to be connected between the live wire and the lamp (electrical appliance) after being connected, and the selection of the binding post affects the action effect (the two connecting wires between the switches need to be connected to the stationary contact).

Note: a stair switch based on single line connection generally indicate to use a lamp of two on-off control or other electrical apparatus.

Example 1 a lamp was controlled with two switches.

(1) The two switches are placed in the appropriate or predetermined positions, respectively.

(2) The two switches are connected by a connecting wire and then connected between the live wire and the lamp (the other end of the lamp is connected with the zero wire).

(3) When the movable contact of a certain switch (left side) is connected with the fixed contact C: when the moving contact of the other switch (right side) is connected with the fixed contact C, the rectifier diodes on the two switches enable the passing directions of the current to be consistent, and the current passes through the bulb (bright); when the moving contact of the other switch (right side) is connected with the fixed contact D, the rectifier diodes on the two switches enable the current to pass in opposite directions, and the current cannot pass through the bulb (be extinguished).

(4) When the movable contact of a certain switch (left side) is connected with the fixed contact D: when the moving contact of the other switch (right side) is connected with the fixed contact D, the rectifier diodes on the two switches enable the passing directions of the current to be consistent, and the current passes through the bulb (bright); when the moving contact of another switch (right side) is connected with the fixed contact C, the rectifier diodes on the two switches make the current pass through in opposite directions, and the current can not pass through the lamp bulb (be extinguished).

Note: in the use, the wiring terminals A and B are used for connecting the two switches, and when the moving contacts of the two switches are connected with the fixed contact C or D, current passes through; when the moving contact of the two switches is connected with the fixed contact C and the other is connected with the fixed contact D, current cannot pass through. If the wiring terminals A and A or B and B are used for connecting the two switches, current cannot pass when the movable contacts of the two switches are connected with the fixed contacts C or D; when the moving contact of the two switches is connected with the fixed contact C and the other one is connected with the fixed contact D, current passes through. Therefore, the selection and the sequence of the binding posts do not influence the action effect.
