How to Use P31 Small Float Level Control Switch Plastic Float Switch
Install the P31 float switch vertically through a bulkhead or bracket so the float can move freely with liquid level changes. Connect its two leads to your pump or alarm circuit, ensuring the load does not exceed 10 W at 220 V. As the liquid rises, the float toggles the internal contacts to activate or deactivate your equipment.
