Liquid Water level sensor Side Mounted Float Switch (liquid level side mounted)

Description:

The liquid level switch detects the rising level of liquid in a sump or tank. It can be connected to a micro controller. It can then be used to start/stop a pump which then pumps liquid in/out until the level of the liquid has been restored to the point where the pump is switched off again. The switch may be used in a pump station, a sensor, a tank alarm, or other devices.
