Zusammenfassung:PROBLEM TO BE SOLVED: To provide a switching device capable of accomplishing a greaseless structure of a ring contact to slide with a movable lead and preventing the ring contact and the movable reed from increasing in their wear and contacting resistance. SOLUTION: The switching device is structured so that the ring contact 13 having electric conductiveness to contact slidably with the movable reed 11 and also contacting with an electric conductive housing 12 is installed between the movable reed 11 and the housing 12, wherein the height of the ring contact 13 is made good larger than the sliding distance of the movable reed 11 when the switch is put on and off.
