| 摘要 |
Provided is a reliable switch having a contact surface that is prevented from being roughened. To solve the problem, there is provided a switch including a plurality of switching units 2 and 3 each including a fixed electrode and a movable electrode that is disposed to be opposed to the fixed electrode and is closed or opened with respect to the fixed electrode, the switch being characterized in that the switching units 2 and 3 each make or break a current to be applied to the switch, the switching units 2 and 3 are electrically connected in series to each other, and the switching units 2 and 3 are each configured such that a first switching unit 3 is first closed, and then a second switching unit 2 is closed. |
