4 Pcs ZP4510 Liquid Water Level Control Sensor Straight Float Switch RC Wheels This Cylinder features:32m bore andA 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. It can be easily converted from normally open to normally close by invertin the float. Note: because the current that the switch can carry is much little(above 0. 5A), you must use a relay or contactor when it is connected by a load, relay and contactor are not included here.
