Abstract:
PURPOSE:To confirm opening/closing of gas plug from the position separated sufficiently from gas stop plug by detecting the position of knob and transmitting an open/close state signal without employing open/close state signal wiring. CONSTITUTION:Under open state of gas stop plug 1, a permanent magnet chip 4 is separated sufficiently from magnetic detection circuit 5 while upon turning a knob 2 to the right to bring closed state of gas stop plug 1, the magnetic detection circuit 5 will face against the permanent magnet chip 4 thus to detect the magnetic force of said magnet 4. Said circuit 5 will receive the detected radio wave signal 13 thus to inform the open/close state of gas stop plug at the position remote from said plug 1.
