The direction wheel has one-degree of rotational freedom and two-degree of freedom to perform clicking, forward rolling, backward rolling, leftward moving and rightward moving operations. Thereby mating electrodes are electrically connected to generate corresponding signals. In normal conditions, the toggle mechanism and a movable contact jointly support the direction wheel. When the direction wheel is depressed, the toggle mechanism drives and connects a corresponding electrode to generate a click signal.

Abstract: A luminous micro-switch mainly includes a case which holds a depressing member and at least a first pin and a second pin inside that are spaced from each other. There is a bridging member interposed between the two pins and the depressing member to form electric connection with the first pin in regular conditions and output a signal when the bridging member is connected to the second pin due to depressing of the depressing member. The depressing member has a depressing end which has a holding trough to hold a lighting element which has two conductive terminals to receive electric power to generate light. By holding the lighting element in the holding trough the size of the micro-switch can be made smaller to be used on smaller electronic devices to overcome the bulky problem of conventional micro-switches caused by disposing the lighting element beneath the depressing member.
