Abstract

The utility model discloses a multiple switch which comprises a switch seat, movable contacts, static contacts and wire connecting terminals. The multiple switch is characterized in that the two movable contacts are linked and have two states. When the multiple switch is in the first state, the two movable contacts are respectively communicated with the first static contact and the third static contact; when multiple switch is in the second state, the two contacts are disengaged from the first state, the two movable contacts are respectively communicated with the second static contact and the third static contact, the first static contact and the fourth static contact are communicated by a connecting line and lead out the first wire connecting terminal, the second static contact and the third static contact are communicated by a connecting line and lead out the second wire connecting terminal. The switch also has the functions of single-link switches and duplex switches, can control the switching of an electric lamp on multiple places and has the advantages of simple structure and control wiring, low cost and convenient operation and maintenance.

Description

Multigang switch

The utility model relates to a kind of electric switch, especially controls the switch that electric light is bright or go out.

Control electric light switch great majority bright or that go out are flat switch and pulling switch at present, and are simply connected or duplex basically.The switch of simply connected is that a switch is at electric light of the three unities control; The switch of duplex can be that two switches can be controlled an electric light in two places respectively, and for example, an electric light in the middle of long two ends, corridor control is located at the corridor, or the electric light in the middle of two floors can be controlled on each floor respectively.But if will be at electric light of plural ground point control, so, simply connected or ganged switch just can't have been accomplished, and in actual life and work, how the needs of an electric light of point control but exist, for example, and the control of the stair light of multi-story; The control of an illuminating lamp in many people guest room; Perhaps the many resident families in unit are to the control of gate, unit electric switch etc.Certainly, lamp of multiple spot control or the means that electrical equipment also can use numerical control, computer control or other automation to control, but its cost can increase greatly, control circuit complexity, the difficulty of increase installation and maintenance.

The purpose of this utility model provides a kind of multigang switch, and it should be able to realize many ground electric light of point control or an electrical equipment, and each switch can both be controlled the on and off of lamp, the perhaps switching electricity of control apparatus, and, simple in structure, cost is low, and control circuit is simple, use and easy to maintenance.

The utility model multigang switch comprises switch base, moving contact, fixed contact and binding post, is characterized in:

The first and second two moving contacts link, and two states are arranged;

When first state, this two moving contact is connected with first and the 3rd fixed contact respectively; When second state, this two moving contact is connected with the second and the 4th fixed contact respectively;

First fixed contact and the 4th fixed contact are connected with line, and draw first binding post; Second fixed contact and the 3rd fixed contact are connected with line, and draw second binding post.

The multigang switch of said structure should comprise that also annexes such as terminal screw, joystick or button could constitute a complete switch product, mainly contain the moving contact of two interlocks, four fixed contacts and two lead-out wire terminals in this switch, simple in structure, cost is low, and volume and existing pulling switch or flat switch are very nearly the same.From its structure as can be known, line is at most two to advance scene 2, control circuit is simple, operation and maintenance is convenient, performance with simply connected, ganged switch, if the control circuit that is used for simply connected or duplex is then simpler, especially for the control circuit of the lamp in two places, between two multigang switches only with two lines.This multigang switch is used for one of many ground point control when electric, and each switch is this lamp of may command bright or go out all, also can be applied to the switching of an electrical equipment of many ground point control.This multigang switch is the regeneration product of existing simply connected, ganged switch.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Shown in Figure 1, be the utility model first structure graph.

Shown in Figure 2, be the utility model second structure graph.

Shown in Figure 3, be the winding diagram that the utility model is applied to an electric light of many ground point control.

By in first status architecture of Fig. 1 as can be known, multigang switch mainly comprises the first moving contact A ₁, the second moving contact A ₂, four fixed contact B ₁～B ₄, binding post C ₁And C ₂Constitute, wherein, first, second moving contact A ₁A ₂Link.When first state, the first moving contact A ₁With the first fixed contact B ₁Connect; The second moving contact A ₂With the 3rd fixed contact B ₃Be communicated with.The first fixed contact B ₁By line and the 4th fixed contact B ₄Be communicated with, and draw the first binding post C ₁The second fixed contact B ₂By line and the 3rd fixed contact B ₃Be communicated with, and draw the second binding post C ₂

Shown in Figure 2, be two moving contact A among Fig. 1 ₁And A ₂The residing state in interlock back is second state, and all the other structures are constant.In second state, the first moving contact A ₁With the second fixed contact B ₂Connect; The second moving contact A ₂With the 4th fixed contact B ₄Connect.

Shown in Figure 3, be the winding diagram that multigang switch is applied to an electric light of many ground point control.A plurality of multigang switch K ₁～K _n, can place the bright of n place (wherein, n is a natural integer) control electric light L or go out.Because K switch ₁～K _nBe schematic structure, so the with dashed lines frame.Power supply Q is generally alternating current 220V, the end of power supply Q and first multigang switch K ₁Moving contact A ₁Or A ₂Connect, the termination of the other end and electric light L is logical; The other end of electric light L and the last multigang switch K _nBinding post C ₁Or C ₂Connect.Between adjacent two multigang switches that are linked in sequence, the first binding post C of a last switch ₁The first moving contact A with next switch ₁Connect with line; The second binding post C of a last switch ₂The second moving contact A with next switch ₂Connect with line, at moving contact A ₁, A ₂With fixed contact C ₁, C ₂But between also interconnection.As can be known from Fig. 3, the multigang switch K at two ends ₁And K _nOnly connect three turnover lines, middle multigang switch K ₂～K _N-1, then need connect two lines that advance scene 2.By also releasing among Fig. 3: when bright with electric light of multigang switch control or when going out, as long as with any one moving contact A of multigang switch ₁Or A ₂With any one binding post C ₁Or C ₂, be serially connected with in power supply Q and the loop that electric light L becomes and get final product.In like manner, when with two multigang switches during at electric light of two places point control, the input of power supply Q can meet a moving contact A of first multigang switch arbitrarily ₁Or A ₂, output can meet the binding post C of second multigang switch arbitrarily ₁Or C ₂, the moving contact A of second multigang switch ₁And A ₂Meet the binding post C of first multigang switch respectively ₁Or C ₂

The moving contact A of this multigang switch ₁And A ₂, binding post C ₁And C ₂, this moving contact and terminals all can be used as output or input point in actual applications, needn't strictly distinguish, and the function of realization is the same.This switch can replace existing simply connected or ganged switch product.
