Abstract
A jack having switch is constituted so that a movable armature is displaced so as to be separated from a fixed armature which contacts with the movable armature by insertion of a plug, the plug and the movable armature are brought into a contact state, and this state is maintained. The movable armature has two-pronged branch portions along a plug insertion/uninsertion direction, and the branch portions have plug contact portions which are expanded to be displaced outward by the plug to be inserted therebetween and hold the outside of the plug so as to be connected to the plug. The branch portions have fixed armature contact portions which contact with the movable armature arranged to be opposed to the branch portions when the plug is not inserted.
