PROBLEM TO BE SOLVED: To provide a push-button switching device in which carrying out of two-stage switching precision is made possible without changing an operation direction by the operator. SOLUTION: A cabinet (10) comprises a protruding part (2) deployed at a prescribed fixed position in a reciprocating direction of an operating piece (1), and a movable contact point (4) arranged at a position on the opposite side of the fixed position where the protruding part (2) is deployed, while a first switch (3) is mounted on the protruding part (2), and the movable contact point (4) becomes a second switch (4). Then, when the tip part of the operating piece (1) is contacted with the first switch (3) mounted on the protruding part (2) by a movement of the operating piece (1), the first switch (3) becomes conductive, the tip part of the operating piece (1) is lively guided by the protruding part in a direction to push the movable contact point (4), and when the tip part of the operating piece (1) presses the movable contact (4), the second switch (4) becomes conductive.
