Patent ID: 7186931

Claim:
A button fastening device with circuit actuating capability, comprising: a first button part; a second button part engageable releasably with said first button part for fastening articles together; and a circuit actuating unit provided on at least one of said first and second button parts, adapted to be electrically connected to a circuit, and operable to control circuit states of the circuit through engagement and disengagement of said first and second button parts; wherein said circuit actuating unit includes first and second conductive members which are adapted to be connected to the circuit, said circuit actuating unit being operable through engagement and disengagement of said first and second button parts to control electrical connection and disconnection between said first and second conductive members; wherein said first button part defines an inner space therein, said first and second conductive members being mounted in said inner space, said second button part having a protrusion that is associated with said first and second conductive members in such a manner that extension of said protrusion into said inner space and removal of said protrusion from said inner space enable electrical connection and disconnection between said first and second conductive members; and wherein said first button part is provided with a retaining member that is mounted in said inner space and that includes a pair of opposite spring arms, said protrusion of said second button part being resiliently clamped by said spring arms when said second button part engages said first button part.
