Claims

[Scope of utility model registration request]

A detection switch with a switch contact and a non-magnetic member exposed on the upper surface of an insulating plate is installed in the lower part of the guide tube, which has a mounting member attached to the top wall of the liquid tank in the upper part, and the guide tube can be slid freely. At the same time, a float adapted to be able to contact the detection switch case is fitted, and a float magnet is provided on the lower surface of the float to bridge the switch contacts by contacting the detection switch case and at the same time attract the non-magnetic member. A float-type liquid level sensor characterized in that a detection signal extraction lead wire connected to a switch contact is passed through a center hole of a guide tube and pulled out from the upper end.
