徴とするレベルスイツチ。 In the electrode rod mounting structure of an electrode type level switch which detects the liquid level in the storage tank by means of an electrode rod installed vertically in the liquid storage tank, a lid is attached to the upper opening of the liquid storage tank in a watertight manner. a member, a cylindrical socket having a flange at the upper part that fits tightly into the through hole drilled in the lid member, and a male threaded part on the outer periphery of the upper part of the flange; a tapered packing to be inserted into the taper packing, an electrode rod-shaped body to be inserted into the center hole of the tapered packing, and a fastener to be inserted into the outer circumference of the electrode rod-shaped body so that its lower end surface abuts the upper surface of the taper packing. the tightening sleeve; and a cap nut having a female thread on the inner circumferential surface that presses the tightening sleeve downward and which can be screwed into the male thread of the socket, and the cap nut is screwed into the upper outer periphery of the socket. At this time, the taper packing is pressed and compressed by the lower end surface of the tightening sleeve, and at least the lower end edge of the taper packing has an inclined surface at an angle smaller than the taper angle of the taper packing so that it can come into annular line contact with the upper inner circumferential surface of the socket. A level switch characterized in that: is formed on the upper inner circumferential surface of the socket.
