The switch can activate a pump, an indicator, an alarm, or other device. It can be easily converted from normally open to normally closed by inverting the float. Note: Since the current that the switch can carry is very small (0.5A), you need to use a relay or contactor when it is connected to a load; the relay or contactor is not included here. As the product batch is different, the cable color may be different; we will ship randomly. Package Contents: 5pcs x Water Level Sensor
