Abstract: A liquid level detecting apparatus having detachable terminals and capable of holding down the formation of silver sulfide is provided. The apparatus includes a movable contact displaced in accordance with the fluctuation of a liquid level, electrodes slidingly contacted by the movable contact on a circuit board, a first resistance connected to the electrodes, and connecting portions which the terminals contact, a resistance value of the first resistance which varies when the movable contact is slidingly moved on the electrodes being outputted from the terminals via the connecting portions, wherein the sections of the connecting portions which contact at least the terminals are covered with second resistances.

Abstract: A liquid level detecting apparatus 1 having detachable terminals and capable of holding down the formation of silver sulfide is provided. The apparatus includes a movable contact 2 displaced in accordance with the fluctuation of a liquid level, a slide 5 slidingly moved at the movable contact 2 on a circuit board 4, a resistance 7 connected to the slide 5, and connecting portions 8 which the terminals 9 contact, a resistance value of the resistance 7 which varies when the movable contact 2 is slidingly moved on the slide 5 being outputted from the terminals 9 via the connecting portions 8, wherein the sections of the connecting portions 8 which contact at least the terminals 9 are covered with second resistances 16.
