A float switch is a device used to sense the level of liquid within a tank.

• The switch may actuate a pump, an indicator, an alarm or other device: because the current that the switch can carry is just 500mA, you must use a relay or contactor(not included).
• It can be easily converted from normally open to normally close by inverting the float.
• Due to product batch is different, cable color may be different, we will random shipment.
