Further, the device also comprises a base; the base is located the bottom of base plate, and when the commutation switch hung at the electronic box, commutation switch's bottom plate and base contact.

Further, the insertion block is provided with a locking part; when the insert block is inserted into the body to a predetermined depth, the locking portion contacts the opening of the body, preventing the insertion of the insert portion.

Further, the insertion block is fixed on the upper surface of the shell of the phase change switch through an integral molding method.

3. Has the advantages that:

the utility model provides a multi-functional commutation switch includes buckle structure, and the one end of buckle is used for linking to each other with the electronic box is fixed, and the portion of inserting of buckle is integrative with commutation switch's shell. Insert the cavity of base member with the inserted part of buckle structure when needing to hang commutation switch in the electric box, when needing to take commutation switch out and inspect, only need inwards to pinch the opening of base member, the elasticity triangle-shaped in the base member takes place the deformation, makes vertical board can be easily come out from another angle department of triangle-shaped. Prevent buckle structure deformation in the use at ordinary times, set up the base that adapts to the commutation switch shell at the lower extreme of the base plate of integration.
