Claims

[Scope of claim for utility model registration] (1) A guide member is provided from the opening for installing the oil level switch of the oil tank toward the bottom;
In an oil level switch that detects the liquid level by attaching an electrode to a float that moves up and down along the guide member, the float is formed of two float members that are disposed to spread laterally from the guide member, and An oil level switch characterized in that two float members are equipped with a spring that biases the float members to expand. (2) The oil level switch according to claim 1, wherein the guide member of the float is formed by two parallel electrode rods provided in the oil tank. (3) The electrodes attached to the float are formed by the ends of springs that bias the two float members in the direction of expansion, and the ends of the springs and the two electrode rods form a switch mechanism. The oil level switch according to claim 1. (4) A claim characterized in that when the two float members are folded against the elastic force of the spring, the shape of the portion located on the outer surface of the float members is formed into a tapered shape that shrinks downward. Oil level switch described in item 1.
