Abstract

The utility model provides a switch with easy installation and wire saving, which can be used in the occasion where multiple switches control a lamp or other electric appliances. In the switch provided by the utility model, a switch housing 1 is provided with six wire connection pile heads 2 which are arranged by the method of two lines and three rows, wherein, four pile heads of both ends of the groups of wire connection pile heads 2 are connected in the crossing way by a conductor 5, and in addition, two movable contact sheets 3 are arranged back to back. The middle position of each movable contact sheet is respectively butted with the wire connection pile heads of the second row. Both ends of the movable contact sheet are respectively provided with movable contacts corresponding to fixed contacts on the group of three unilateral double end wire connection pile heads. A non-return key 4 is arranged between the two movable contact sheets. The non-return key can be used for conducting the switching between the 1, 2; 2 2 site and the 3, 2; 2, 2 site when the movable contact sheet is operated to conduct the switching between the 1, 1; 2, 1 site and the 3, 1; 2, 1 site.

Description

Switch

The utility model relates to a kind of switch, especially will control the switch that uses in lamps or other electrical equipment occasions with many switches.

Have only ganged switch to sell in the market, ganged switch can only be two switch lamps of control or other electrical equipment, can only not utilize ganged switch to pull on more electric wire between switch and electrical equipment and could realize with regard to there being a kind of special switch in the time will making lamp of more switches control or electrical equipment, this just makes the phenomenon that produces when requiring electrical equipment of many switches control that wiring bothers and waste with line.

At above defective, the purpose of this utility model is exactly that a kind of switch that can be used for an electrical equipment of many switch control will be provided.

Switch provided by the utility model has six to arrange on one side (promptly by 1,1 by two groups three in switch housing 1; 1,2; 2,1; 2,2; 3,1; 3,2 arrangements) wiring pile crown 2 has fixed contact on the wiring pile crown, and wherein four pile crowns in the two ends of two set of connections pile crowns are intersected continuous (promptly 1,1 and 3,2 link to each other, and 3,1 and 1,2 links to each other) by conductor 5, and are isolated with insulator 6 between the conductor.Also have the movable contact spring 3 back-to-back arrangements of two seesaw shapes, the centre position of every movable contact spring respectively with the wiring pile crown in centre on one group of three one side (promptly 2,1 and 2,2) fixed contact on offsets, movable contact spring two ends respectively have one with this group three one side two ends wiring pile crown on the corresponding moving contact of fixed contact, one non-return button 4 is arranged between two movable contact springs, the non-return button has two prominent points that point to two movable contact springs respectively, prominent point the non-return button depressed position and cross over the centre position of movable contact spring when upspringing the position.

In use with the two ends wiring pile crown (1,2 on one group of three one side of last switch provided by the utility model; 3,2) with two groups of a back switch provided by the utility model wiring pile crowns (2,1 in the middle of each; 2,2) link to each other with lead respectively, two groups of the most last switch provided by the utility model each middle wiring pile crowns link to each other with the two ends wiring pile crown of ganged switch, and the two ends wiring pile crown on one group of three one side of last switch provided by the utility model links to each other with the another ganged switch.

As mentioned above, switch provided by the utility model can a plurality ofly arbitrarily seal among two ganged switches, and any switch comprises that ganged switch can arbitrarily control same lamp or electrical equipment, and is easy for installation, wire-saving.
