Claims

[Scope of utility model registration request]

A float switch that controls the liquid level by detecting multiple liquid level positions in response to the up and down movements of a float above the liquid surface, has a magnet attached to the top of a drive shaft connected to the float, and a magnet attached to the top of a drive shaft connected to the float. A normally closed upper limit setting proximity switch provided at a position corresponding to the movement, a normally open lower limit setting proximity switch, a normally open abnormality detection switch, and upper and lower limit stoppers provided on the drive shaft. A float switch characterized in that each of the proximity switches and the magnet are mounted inside a box above the liquid.
