Abstract
Liquid level detectors known in the art are, for the most part, designed so that they are mounted in a vertical direction to the liquid level. However, with the recent trend toward using liquid containers of more complicated shapes, there has existed a need for a liquid level detector of a type that can be mounted in a horizontal direction with respect to the liquid level. Moreover, there has existed a need for a liquid level detector of a type which requires as small a mounting opening as possible. In accordance with the present invention, there is provided a liquid level detector in which a permanent magnet is fixedly mounted on the central portion of a float having a long and slender shape, e.g., elliptic or rectangular shape and being enabled to slide along a case containing a reed switch therein and to positively bring the reed switch into operation to detect the liquid level, and which thus meets the above-mentioned requirements.
