Button fastening device for bags, has circuit actuating unit including conductive units, and operable through engagement and disengagement of button units to control electrical connection and disconnection between conductive units

摘要

A circuit actuating unit (1) has conductive units and is operable through engagement and disengagement of button units (2,3) to control electrical connection and disconnection between conductive units. A button unit defines inner space where conductive units are mounted, and the other button unit has protrusion (10) extending into the inner space.
