チ。 A float that floats on the liquid surface and changes its posture from an erect state to an inverted state depending on the liquid level, a ring-shaped magnet that can move by its own weight along a guide tube inside the float, and A reed switch is disposed inside the guide tube so as to be activated when the magnet is approached, and a sealed chamber enclosing the magnet is formed along the outer circumferential wall of the guide tube. A buffer fluid-filled float switch characterized in that a buffer fluid is sealed to slow down the movement of the magnet.
