Water Level Sensor Float Switch

This Water Level Sensor Float Switch is a device used to sense the level of the liquid within a tank, it may actuate a pump, an indicator, an alarm, or other device.

A compact, horizontally mounted float switch which can be configured as a normally-open or normally-closed switch simply by rotating it through 180°. When the water level reaches the float, the float moves and an internal magnet activates a sealed reed relay in the device. The sensor is supplied pre-wired with fling output leads.
