徴とするフロートスイツチ装置。 A float body is provided, which is composed of a combination of a float that moves according to changes in the liquid level, a pick-up coil, and a magnetic armature that advances and retreats within the pick-up coil in conjunction with the float,
In the float switch device, the pick-up coil is provided with a detection system that detects the upper and lower limits of a predetermined liquid level region from changes in impedance of the pick-up coil, and ON/OFF control is performed in response to the detection signal. An upper and lower area detection system is provided to detect when the liquid level reaches an area directly above and directly below a predetermined liquid level area, and this upper and lower area detection system receives a detection signal from the upper and lower area detection system to notify the liquid level state. A float switch device characterized by being provided with a notification means.
