技术领域

[0001]本实用新型涉及电网配件，尤其涉及拉线开关。

背景技术

[0002]拉线开关一般用于小功率电器的控制，如照明电灯等。拉线开关在使用时，操作人员通过拉动绝缘线控制开关内的转轴转动，从而实现电路的接通或断开;拉线开关由于采用绝缘线控制开关内的部件动作，有效地拉长了带电部件与操作人员的距离，使用时更加安全。

[0003]现有技术的拉线开关结构简单，无法控制多台照明电灯，当需要控制多台电灯时，需要增加多台开关，即增加了成本又减弱了使用的便捷度。

[0032]本实用新型通过外壳中间设置安装铜片电路，且通过开关组件控制铜片电路的导通或断开，灯座与固定座结合固定;开关采用拉杆式可多位控制载体;适用于各种灯具。

[0033]本实用新型的开关组件2包括第一弹簧31、旋转轮32、拉杆33、导电片34和第二弹簧35。旋转轮32包括一筒状的固定部321及设于所述固定部321—侧的限位部322，且所述限位部322包括若干锯齿凸起，所述固定部内侧设有一固定通孔。拉杆33包括一动力部333及一拉动部331，且所述动力部333为所述拉动部331的末端扭转形成，所述拉动部331上设有限位凸起332，所述拉动部331穿过所述固定通孔，且所述拉动部331—侧通过限位凸起332限位，所述第一弹簧31套设于所述动力部333上，所述第一弹簧31两端分别通过所述动力部333的底部及所述旋转轮32限位.导电片34包括导电片主体，且所述导电片主体套设于所述旋转轮的固定部外侧，且所述导电片主体上连接导电触片，且所述导电片主体上设有若干第一转动凸起，所述第一转动凸起可与所述锯齿凸起卡扣，且所述第一转动凸起只能相对于所述锯齿凸起一个方向转动，所述导电触片一端与所述导电片主体连接，且所述导电触片的另一端向远离所述导电片主体方向弯折，所述外壳上还包括若干第二转动凸起(图中未示出)，且所述第二转动凸起可与所述导电触片卡扣，且所述第二转动凸起只能相对于所述导电触片一个方向转动。

[0034]第二弹簧套34设于所述固定部上，所述第二弹簧与所述导电片接触且电性连接，且所述第二弹簧的两端分别通过所述导电片及所述外壳限位。

[0035]本实用新型的铜片电路包括:第一铜线、第二铜线和若干第三铜线，第一铜线设有若干第一连接端21;第二铜线与所述第二弹簧电性连接;所述第三铜线一端设有一第二连接端22，且所述第三铜线的另一端可与所述导电触片电性连接，第一连接端和第二连接端分别连接电路的火线及零线。

[0037]本实用新型的工作原理为:

[0038] 通过拉动拉杆的拉动部，可带动动力部运动，由于动力部为拉动部扭曲形成，因此动力部在向前运动的过程中，带动旋动轮向前运动并同时转动，由于旋转轮上设有锯齿凸起，且该锯齿凸起与导电片上设有的第一转动凸起卡扣，因此旋转轮在转动的过程中带动导电片转动，导电片在转动时，导电触片可与所述第三铜线的另一端电性连接，此过程中旋转轮与导电片卡扣不能相对运动，且导电片相对于外壳可以转动。当施加于拉杆的拉动部上外力消失后，由于第二弹簧的作用，拉杆会退回，退回的过程中会带动旋转轮向后退同时转动，此时导电片相对于外壳不能转动，且旋转轮可对于导电片发生转动。当拉动杆在外力的作用下前后往复运动的过程中，导电片完成与第三导线的第二端电性连接或断开，从而完成开关的导通或断开。

[0039]本实用新型中，第三电线设有三条，因此本开关可同时控制三个电灯，

[0040] 本实用新型还包括一固定座4，其与所述外壳可拆卸且电性连接，且所述固定座可连接一灯泡。所述灯泡与所述固定座的连接方向与所述外壳平行。由于本实用新型的开关在固定时外壳与墙面水平固定，因此固定好的开关上的固定座与墙面平行，当固定座上安装有灯泡时，灯泡的照射范围最大。

[0041]以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
