Abstract
A switching device comprises a movable member which makes the first switch turn to an opposite phase at the first thrust-in position and makes the second switch turn to an opposite phase at the second thrust-in position, a first locking means which locks the movable member at the first thrust-in position, a second locking means comprising a torsion coil spring engaging member and a heart type cam recess on which the engaging member slides, which locks the movable member at the second thrust-in position, and a reset member which releases the movable member from the locking state. The first and second switches are selectable to set and can be alternatively operated only by repeated thrust-operation.
