• a switch having a first touch part and a second touch part;
• and
• a pressing element interposed between the button and the switch, the pressing element including a first end part contacting a first wall of the housing, a second end part contacting the button, a first pressing projection disposed adjacently to the first touch part, a third end part contacting the first wall of the housing, a forth end part contacting the button, and a second pressing projection disposed adjacently to the second touch part;
• wherein when one side of the button is actuated, the second end part pivots upon the first end part in a first direction, while the first pressing projection actuates the first touch part,
• wherein the first end part is aligned with the first wall and a dome of the first touch part along a first axis and the second end part is aligned with the dome of the first touch part and the button along a second axis,
• wherein the first axis and the second axis are substantially parallel to one another,
• wherein when an other side of the button is actuated, the forth end part pivots upon the third end part in the first direction, while the second pressing projection actuates the second touch part,
• wherein the third end part is aligned with the first wall and a dome of the second touch part along a third axis and the forth end part is aligned with the dome of the second touch part and the button along a forth axis, and
