Multidirectional operation key

摘要

A multidirectional operation key including a micro stick switch and a flexible navigation button is provided. The multidirectional operation key, which absorbs the manufacturing and assembly tolerances, is installed in a small-sized electronic device which has an upper cover. The flexible navigation button is used to fine-tune the relative position between the multidirectional operation key and the upper cover such that the multidirectional operation key can perfectly fit into an opening on the upper cover. Of which, the flexible navigation button is a two pieces design including a body and a shaft cover. The upper end of the shaft cover is flexibly jointed with the body while the lower end of the shaft cover is tightly mounted on the micro stick switch with the body being held up by an elastic piece situated between the body and the shaft cover. Besides, the multidirectional operation key further includes an elastic holding piece which holds and keeps the flexible navigation button at a horizontal position.
