This switch will open or close the electric circuit when liquid level reaches a specific position. It can be used to activate a pump when liquid level is low, or to open the heating circuit to prevent the damage of the heater. For activating the pump when liquid level is low, the sensor tip should be mounted downwards as shown in the picture below. For cutting off the heating circuit when liquid level is low, the sensor tip should be mounted upwards. Since the switch is rated for 0.8 Amp, a typical wiring is to put it in series with relay (or solid state relay) control loop.

Dimension in mm. The switch is closed when float is in the position shown in the picture

The switch can be mounted with the float pointing down and set up using the normally open or the normally closed switch option. This will greatly simplify the fabrication of a brewing kettle. All that need to be done is to simply invert the physical float.
