Scroll switch
First Claim
1. An improved scroll switch comprising an encoder mechanism housed in a casing to be disposed in a mouse device, notebook computer, handheld computer or keyboard and to be driven by a roller for actuating the scroll switch to generate an encoded signal output for the computer to process and control windows pages switching, wherein:
- the casing has a housing chamber bordered by two walls at two sides thereof, the walls having respectively a first bore, one wall having a snap aperture located below the first bore; and
the encoder mechanism includes a body, a cap, a press element, a rotary element and a contact element;
the body having a frame which forms an action space therein and an encoder circuit located at one side of the action space;
the cap having a third bore and a snap stub located at one side adjacent the third bore engageable with the snap aperture such that the encoder mechanism is capable of fastening to the casing or be disassembled rapidly.
