Water Level Sensor Plastic Float Switch

Water Level Sensor Plastic Float Switch 

A plastic float switch is a simple and reliable water level sensor used to detect changes in liquid level inside a tank or container. It consists of a hollow plastic float attached to a sealed switch assembly. As the water level rises or falls, the float moves accordingly, causing the internal switch to open or close. The sensor outputs a simple electrical signal that can be used to trigger pumps, alarms, controllers, or other devices. Plastic float switches are lightweight, corrosion-resistant, and suitable for a wide range of water or non-corrosive liquid level applications.
