ABSTRACT:
A zipper switch for the DC motor of a ceiling fan has an upper shell and a lower shell. The upper shell is pivotally disposed with an activating disk, an elastic element, and a zipper connected with the activating disk. One side of the activating disk has a connecting part that is disposed with a metal plate. Contacts are formed on both sides of the connecting part. The lower shell accommodates the connecting part. A conductive elastic plate is provided on both sides of the metal plate contacts. The rotation of the activating disk enables the contacts of the metal plate to have instantaneous contacts with the corresponding conductive elastic plates that are connected with wires. An instantaneous electrical current is thus produced.
