Summary:The utility model relates to a combination switch, include: the lower cover, install the circuit board of covering under, with the chamber is held with formation to the lower cover assembly will the upper cover of circuit board parcel, and, set up in the upper cover with between the lower cover, be used for with the upper cover is detachable install in the fixed knot who covers down constructs. When last lower cover is installed, construct fixing realization upper cover and lower cover between through the fixed knot who sets up between upper cover and the lower cover to avoided causing the installation clearance leakage, insecure phenomenon owing to buckle structure's damage between upper cover and the lower cover. It is high to make combination switch's shell have an inseparable degree, advantage that the fastness is good. 本实用新型涉及种复合开关，包括：下盖；安装在下盖上的电路板；与所述下盖装配以形成容纳腔将所述电路板包裹的上盖；以及，设置于所述上盖与所述下盖之间的、用于将所述上盖可拆卸式安装于所述下盖上的固定结构。在上下盖安装时，通过上盖与下盖之间设置的固定结构，实现上盖与下盖之间的固定，从而避免了上盖与下盖之间由于卡扣结构的损坏而造成安装不紧密，不牢固的现象。使得复合开关的外壳具有紧密度
